Q1.
The knowledge of research methods is valuable as a consumer of research for many reasons. When this topic is discussed, the initial thought is that researching gives individuals’ ideas and information on the topic they are researching. It also gives them the tools needed to learn how to problem solve and think analytically. This is an important factor because this will allow the consumer to learn more about the topic in questions and be better educated in the subject. Along with this, the knowledge of research methods is valuable because it allows consumers to learn the techniques of being a successful researcher.
Research methods provide individuals with ideas, tools and approaches on how to be a successful consumer of research. If a consumer does not know the technique on how to approach research, they can spend hours studying materials and resources that may not be useful to their research. Knowing how to approach the two types of research, research to learn and research to contribute, will help a consumer determine the most effective approach to research with the best outcome. Beginning this process starts with revisiting the scientific method, which although seems elementary, is very efficient in the research process.
Consumers of scholarly research are individuals who use sources of research that were done by an accredited institution and have prebias or a set agenda based opinions they are trying to prove through the research. Research conducted by accredited institutions have a higher quality of factual information researched and are well respected. When consumers of scholarly research are attempting to prove their point, or their agenda, they seek out well respected sources to solidify the swaying of opinions readers may have about their research.
Conducting actual research can be referred to as research to contribute, as the consumer is taking part in the hands-on research, exploring information and piecing together items to prove a theory. The more research you do hand on, the more knowledge you gain about the topic you are researching. It also provides better leverage in being able to prove a theory you are trying to present. Conducting research can be followed by the scientific method to help establish a successful research project.
The credibility and reliability of peer reviewed sources can be debated based on the scholarly sources. In a peer reviewed journal, it was debated whether or not if articles published in peer reviewed and throw away journals were reliable sources. “Although lower in methodologic and reporting quality, review articles published in throwaway journals have characteristics that appeal to physician readers.” (Rochon). Surprisingly, in a peer reviewed article, it was found that even research literature without highly reputable academic sources are enjoyed and read by researchers and individuals seeking informative sources. This would not be the ex.

Writing an Effective Literature Review provides guidance on conducting a literature review. It advises researchers to begin by asking questions to ensure their topic is worthy of study and they have sufficient knowledge. A literature review assesses previous scholarly work on a topic by collecting, evaluating, and interpreting relevant literature. It helps focus the research, identify gaps, and build on existing ideas and theories. The document outlines the steps to search literature sources effectively, evaluate findings, organize the review, and avoid plagiarism.
Finding Sources of EvidenceAn important step in the EBP process .docxRAJU852744
Finding Sources of Evidence
An important step in the EBP process is reviewing the current body of literature to better understand the subject or topic in which you are interested. By conducting a review of the literature, you are building foundational knowledge about the topic; later, you can use this background to build new insights. Developing a strong grasp of a topic can only be garnered by taking the time to thoroughly search for relevant information and resources.
For this Discussion, you will practice searching the literature to find evidence on a specific topic.
To prepare:
Choose a simple search term(s) relating to a topic of your PICOT question.
Review the information on the evidence hierarchy discussed in Chapter 2 of the course text, in the article, “Facilitating Access to Pre-Processed Research Evidence in Public Health,” and in the multimedia presentation “Hierarchy of Evidence Pyramid,” found in this week’s Learning Resources.
Review the information on the Walden Library’s website, “Levels of evidence.” Take a few minutes to explore the different types of databases available for each level of evidence and focus on the meaning of filtered and non-filtered resources.
Conduct a literature search in the Walden Library on your selected topic using the databases that you reviewed. Use at least one database for each of the three levels of filtered information and at least one unfiltered database. Record the number of hits that you find at each level of the hierarchy of evidence.
Select one article from the results at each level of the hierarchy. Compare the articles based on the quality and depth of information. What would be the value of each resource if you were determining an evidence-based practice?
Post a summary of your search. Describe what topic you selected, the search term(s) that you used, and the number of results found at each level of the hierarchy. Compare the types of information found in the articles from different levels and the value of the information from each level. Highlight a useful tip that you could share with your colleagues about conducting an effective literature search.
Read a selection of your colleagues’ responses.
Respond to at least two of your colleagues on two different days using one or more of the following approaches:
Share an insight from having read your colleagues’ postings, synthesizing the information to provide new perspectives.
Validate an idea with your own experience and additional sources.
Make a suggestion based on additional evidence drawn from readings, or after synthesizing multiple postings.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Dr.TDS. UBDTCE-DVG
13. How To Review The Literature
4/17/2024 13
Dr.TDS. UBDTCE-DVG
14. Start with broad ideas, gradually narrowing down your focus
Avoid reviewing literature without a specific research problem to prevent
biasing your thinking
Conceptualize your research problem broadly before conducting a major
literature review
4/17/2024 14
Dr.TDS. UBDTCE-DVG
15. What is known in the area?
What is not known or the gaps in the existing body of knowledge?
What questions remain unanswered?
Are there any areas of professional conflict?
What theories are relevant to your area of research?
What suggestions exist for further research?
What research strategies have others used in similar research?
Your literature search should concentrate
4/17/2024 15
Dr.TDS. UBDTCE-DVG
16. There are four steps involved in conducting a literature review
1. Searching for the existing literature in your area of study.
2. Reviewing the selected literature.
3. Developing a theoretical framework.
4. Developing a conceptual framework.
4/17/2024 16
Dr.TDS. UBDTCE-DVG
18. Define your research subject and problem, as well as the study
population.
Compile a bibliography from books, journals, conference papers, and
the Internet
1. Books
Books provide quality content but may lack timeliness.
Search library catalogs using subject headings and keywords.
Compile a list of 10-15 essential books based on bibliographies.
Verify relevance and create annotated bibliographies.
Track references using a card index or reference management software.
4/17/2024 18
Dr.TDS. UBDTCE-DVG
19. 2. Journals
Journals provide current information, typically with a 2-3 year delay.
Find journals through hard copies, abstract indices, or online databases.
Make a list of journals and articles to review.
Check contents pages, read abstracts, and note relevant articles.
Use resources like Humanities Index and ERIC(Educational Resources
Information Center) for easier searching.
Access indexing services online or in print.
Use library computers for searching by subject, author, or title, and
keywords.
4/17/2024 19
Dr.TDS. UBDTCE-DVG
20. 3. Conference papers
Access papers from recent professional conferences for the latest
research in your field.
4. The Internet
The internet allows quick access to published literature.
Use Google, scholar.google.com, or Yahoo! for searches.
Sci hub doi.org/10.1016/j.triboint.2022.107864
Be cautious with Wikipedia for academic purposes.
4/17/2024 20
Dr.TDS. UBDTCE-DVG
21. Common databases cover public health, sociology, education, and business
studies.
Internet searches, like library catalog searches, use keywords to find relevant
material in search engine databases.
Internet searches utilize Boolean logic (AND, OR, NOT).
The citation keyword usage with these operations streamlines searches
(Gilbert, 2008: 73), This helps in finding relevant references.

topic.
4/17/2024 28
Dr.TDS. UBDTCE-DVG
29. 6. Use theoretical framework as a guide for literature review.
7. Begin with general information and gradually narrow down to specific aspects
Example: Review literature on fertility and mortality relationship
Fertility trends, theories, factors affecting fertility, contraceptive methods.
Mortality factors, indices, trends.
Relationship between fertility and mortality theories.
Example
Status of IT in Agriculture Marketing in Karnataka: This literature review includes
books and articles from 1995 to 2016 by various authors who have contributed to the
field of agriculture marketing.

Rural Women in Karnataka
4/17/2024 29
Dr.TDS. UBDTCE-DVG
30. 8. Write literature review under headings
Example: Review literature on fertility and mortality relationship
Fertility theories
Theory of demographic transition
Trends in fertility
Contraceptive methods
Factors affecting mortality
Trends in mortality
Measurement of mortality indices
Relationships between fertility and mortality theories.
4/17/2024 30
Dr.TDS. UBDTCE-DVG
32. 1. Conceptual framework: Basis of research problem, derived from
theoretical framework.
2. Theoretical framework: Consists of theories or issues in study.
Conceptual framework selects aspects from theoretical framework for study.
Example: Theoretical framework includes fertility-mortality theories, while
conceptual framework may focus on testing one theory like fear of non-
survival.
Conceptual framework specifically relates to research problem and becomes
study foundation.
4/17/2024 32
Dr.TDS. UBDTCE-DVG
33. Writing about the literature reviewed.
4/17/2024 33
Dr.TDS. UBDTCE-DVG
34. To write about the literature reviewed, focus on two main functions:
providing a theoretical background and
identifying gaps or recent advances in the field.
For example, if studying the relationship between mortality and fertility:
1. Review literature on fertility and mortality, including theories, factors
affecting fertility, contraceptive methods, mortality factors, and their
relationship.
4/17/2024 34
Dr.TDS. UBDTCE-DVG
35. 2. Develop a theoretical framework focusing on theories explaining the
relationship, such as economic, religious, medical, and psychological
perspectives, and specific theories like insurance theory, fear of non-
survival, and replacement theory.
3. Organize literature review under headings like fertility theories,
demographic transition theory, fertility trends, contraceptive methods,
mortality factors, trends in mortality, and relationships between fertility and
mortality theories.
4. This literature review provides the theoretical background for your study,
laying the foundation for further research and analysis

4/17/2024 38
Dr.TDS. UBDTCE-DVG
39. The overall research design can be divided into:
(a) Sampling Design: Method of selecting items for observation.
(b) Observational Design: Conditions for making observations.
(c) Statistical Design: Determining sample size and analysis methods.
(d) Operational Design: Techniques for carrying out specified procedures.
4/17/2024 39
Dr.TDS. UBDTCE-DVG
40. A research design must specify:
Relevant information sources and types.
Data gathering and analysis approaches.
Considerations for time and cost.
In brief, it should include:
a clear research problem statement;
data collection procedures;
target population; and
data processing and analysis methods.
4/17/2024 40
Dr.TDS. UBDTCE-DVG
42. Research design:
Maximizes efficiency in operations, Guides project direction,
Requires careful preparation, Ensures reliable results.
Skipping a good research plan leads to bad results.
Prior planning is essential for improvement.
Critics struggle without a solid research plan.
4/17/2024 42
Dr.TDS. UBDTCE-DVG
43. Features of a Good Design
4/17/2024 43
Dr.TDS. UBDTCE-DVG
44. A good research design is flexible, appropriate, efficient, and economical.
It minimizes bias and maximizes data reliability.
Provides maximum information and considers various aspects of the
problem.
However, its suitability varies depending on the research problem.
A research design suitable for a specific problem involves considering:
How to gather information
Researcher and staff availability and skills
The problem's objective
The problem's nature
Time and budget constraints
4/17/2024 44
Dr.TDS. UBDTCE-DVG
45. Exploratory studies need flexibility
Descriptive studies prioritize accuracy.
Testing causal relationships requires causal inference capability.
Categorizing studies can be complex.
Choice of research design depends on primary function and factors like
time, budget, staff skills, and data collection methods.
4/17/2024 45
Dr.TDS. UBDTCE-DVG
47. Before discussing research designs, let's explain related concepts for
clarity.
1. Dependent and independent variables:
Variables can be quantitative (e.g., weight) or qualitative (e.g.,
presence of attributes).
Quantitative variables can be continuous (e.g., age) or discrete
(e.g., number of children).
Dependent variables rely on independent variables (e.g., height
depends on age).
Ready-made films and lectures are independent; behavioral
changes are dependent.
4/17/2024 47
Dr.TDS. UBDTCE-DVG
48. 2. Extraneous variable:
Extraneous variables can affect the dependent variable.
In a study on children's achievement and self-concepts, intelligence
could be one.
Effects from these variables are called "experimental error."
A good study attributes effects on the dependent variable solely to the
independent variable(s).
3. Control:
Minimizing extraneous variable influence is crucial in research
design.
Control involves reducing these variables' effects.
In experiments, control means maintaining consistent conditions.
4/17/2024 48
Dr.TDS. UBDTCE-DVG
49. 4. Confounded relationship:
Extraneous variables affecting the dependent variable cause
confounding.
Confounding occurs when extraneous variables influence the
relationship between variables.
5. Research hypothesis:
A research hypothesis predicts a relationship between variables.
It requires objective verification through scientific methods.
Unverified predictions or untested relationships are not research
hypotheses.
4/17/2024 49
Dr.TDS. UBDTCE-DVG
50. 6. Experimental and non-experimental hypothesis-testing research:
Hypothesis-testing research tests hypotheses.
It can be experimental (manipulating the independent variable) or non-
experimental.
For example, studying intelligence's effect on reading ability
without manipulation is non-experimental.
Testing training program effectiveness by manipulating program
type is experimental.
4/17/2024 50
Dr.TDS. UBDTCE-DVG
51. 7. Experimental and control groups:
In experimental research, one group has usual conditions (control group)
while another has novel conditions (experimental group).
Studies may involve only experimental groups or both experimental and
control groups.
8. Treatments:
In experiments, conditions for groups are called 'treatments.'
For instance, when comparing fertilizers' impact on wheat yield, each
fertilizer variety is a treatment.
4/17/2024 51
Dr.TDS. UBDTCE-DVG
52. 9. Experiment:
Experimentation tests hypotheses.
Absolute experiments assess single factors, like fertilizer impact.
Comparative experiments compare different factors, like two fertilizers.
Comparative experiments common in experimental design discussions.
10. Experimental unit(s):
Experimental units are predefined plots or blocks where treatments are
applied.
Selecting or defining experimental units requires careful consideration.
4/17/2024 52
Dr.TDS. UBDTCE-DVG
54. Research designs can be categorized as follows:
(1) exploratory research studies;
(2) descriptive and diagnostic research studies; and
(3) hypothesis-testing research studies.
1. Research design in case of exploratory research studies
Exploratory research, also known as formulative research, aims to formulate
a problem for further investigation or develop working hypotheses.
Three common research design methods for exploratory studies are:
(1) Literature survey (2) Experience survey (3) Analysis of 'insight-
stimulating' examples
4/17/2024 54
Dr.TDS. UBDTCE-DVG
55. i. Literature survey: Review past research to form new hypotheses.
Bibliographical survey:
Explore relevant studies to refine research questions.
Apply diverse concepts:
Use theories from different fields to inform the study.
Creative sources:
Gain insights from creative works for hypothesis formulation.
ii. Experience survey
Interview experienced individuals.
Understand relationships and ideas.
Choose capable respondents.
Send questions early for thoughtful
responses.
Clarify research problems.
Provide insights for various research
methods
4/17/2024 55
Dr.TDS. UBDTCE-DVG
56. .
iii. Analysis of ‘insight-stimulating’ examples
Analyzing examples generates hypotheses in new areas.
It involves studying specific instances using records or interviews.
Key factors: researcher attitude, thoroughness, and information synthesis.
This method uncovers insights by examining examples deeply.
Choose examples based on the problem.
Examples: reactions of strangers, marginal individuals, transitions, or diverse
backgrounds.
Cases with sharp contrasts or striking features are most helpful.
Flexibility is crucial in exploratory research to address various aspects..
4/17/2024 56
Dr.TDS. UBDTCE-DVG
57. 2. Research design in case of descriptive and diagnostic research studies
Descriptive research describes, while diagnostic research determines
frequency or associations.
Diagnostic studies check if variables are associated, while descriptive studies
predict outcomes or narrate facts about individuals, groups, or situations.
Both need clear goals, methods, and target groups.
Planning is vital for accuracy, minimizing bias, maximizing reliability, and
managing costs.
4/17/2024 57
Dr.TDS. UBDTCE-DVG
58. 1. Formulating the objective of the study (what the study is about and why
is it being made?)
2. Designing the methods of data collection (what techniques of gathering
data will be adopted?)
3. Selecting the sample (how much material will be needed?)
4. Collecting the data (where can the required data be found and with what
time period should the data be related?)
5. Processing and analysing the data.
6. Reporting the findings.
Research Designs should be strict and focus on
4/17/2024 58
Dr.TDS. UBDTCE-DVG
59. Clear objectives are crucial in descriptive/diagnostic studies for relevant data collection.
Careful selection of data collection methods is essential, considering their strengths and
weaknesses.
Supervision of field workers is necessary to minimize errors.
Data processing involves coding, tabulation, and statistical computations, requiring careful
planning.
Checks for coding accuracy and precision in tabulation are important.
Statistical operations and significance tests are needed to draw valid conclusions from the study
Efficient reporting in a well-planned report is crucial.
The research design for descriptive/diagnostic studies minimizes bias and maximizes
reliability, considering objectives and resources.
This design resembles a survey design, covering all steps in studying a phenomenon.

Dr.TDS. UBDTCE-DVG
61. 3. Research design in case of hypothesis-testing research studies:
Experimental studies test causal relationships between variables.
They aim to reduce bias, increase reliability, and infer causality.
Professor R.A. Fisher developed experimental designs, initially in agricultural research
Fisher's approach involved dividing fields into blocks for more reliable experiments.
Experimental designs, despite agricultural origins, are widely used across disciplines.
Technical terms like treatment, yield, plot, and block are commonly used in
experimental design.
4/17/2024 61
Dr.TDS. UBDTCE-DVG
62. Basic Principles of Experimental Designs
Professor Fisher established three principles of experimental designs
4/17/2024 62
Dr.TDS. UBDTCE-DVG
63. 1. Principle of Replication:
Repeat experiments to enhance statistical accuracy.
Apply treatments across multiple units to obtain reliable results.
Increases precision but complicates computational analysis.
Aim is to improve accuracy in estimating main effects and interactions.
2. Principle of Randomization:
Randomize experimental conditions to counter extraneous factors.
Design experiments to attribute variations to chance.
Mitigates impact of variables like soil fertility.
Ensures better estimation of experimental error for accurate results.
4/17/2024 63
Dr.TDS. UBDTCE-DVG
64. 3. Principle of Local Control:
Deliberately vary known sources of variability.
Divide experimental area into homogeneous blocks.
Randomly assign treatments within each block.
Allows isolation of treatment effects from extraneous factors.
Enhances reliability of experimental outcomes
4/17/2024 64
Dr.TDS. UBDTCE-DVG
65. Important Experimental Designs
Experimental designs are informal or formal. Informal designs use simpler analysis,
while formal ones offer more control and precise statistical procedures.
4/17/2024 65
Dr.TDS. UBDTCE-DVG
66. i. Informal designs:
1. Before-and-after without control
2. After-only with control
3. Before-and-after with control
ii. Formal designs:
4. Completely randomized design (C.R. Design)
5. Randomized block design (R.B. Design)
6. Latin square design (L.S. Design)
7. Factorial designs
Each design serves specific purposes, with formal designs providing more control and
rigorous statistical analysis compared to informal ones.
4/17/2024 66
Dr.TDS. UBDTCE-DVG
67. 1. Before-and-after without control design:
Test area:
Level of phenomenon
before treatment (X)
Treatment
introduced
Level of phenomenon
after treatment (Y)
Treatment Effect = (Y) – (X)
Single test group or area selected
Measure dependent variable before treatment
Introduce treatment, measure dependent variable again
Treatment effect calculated: post-treatment level minus pre-treatment level
Challenge: potential for extraneous variations over time
4/17/2024 67
Dr.TDS. UBDTCE-DVG
68. 2. After-only with control design:
Two groups: test area (receives treatment) and control area (does not receive treatment)
Treatment introduced only in test area
Measure dependent variable simultaneously in both areas
Assess treatment impact by comparing dependent variable values between test and
control areas
Assumes both areas behave similarly towards the phenomenon
Risk of extraneous variation if assumption is false
This can be exhibited in the following form:
Test area:
Control Area
Treatment introduced Level of phenomenon
after treatment (Y)
Level of phenomenon without
treatment (Z)
Treatment Effect = (Y) – (Z)
4/17/2024 68
Dr.TDS. UBDTCE-DVG
69. 3. Before-and-after with control design:
Two areas chosen
Measure dependent variable in both areas for same time before treatment
Introduce treatment in test area only
Measure dependent variable in both areas for same time after treatment
Treatment effect calculated by subtracting change in dependent variable in control area
from change in test area
Test area:
Control Area
Time Period 1
Level of phenomenon before
treatment (X)
Level of phenomenon without
treatment (A)
Treatment
Introduced
Level of phenomenon
after treatment (Y)
Level of phenomenon
without treatment (Z)
Treatment Effect = (Y – X) – (Z-A)
4/17/2024 69
Dr.TDS. UBDTCE-DVG
70. Based on two principles: replication and
randomization
Simple and easy to analyze
Subjects randomly assigned to treatments
Equal chance for each group to receive
treatment
Analysis done with one-way ANOVA
Can accommodate unequal replications
Ideal for homogeneous experimental areas
Referred to as C.R. design when variations
are considered chance

4. Completely Randomized design (C.R. design):
4/17/2024 70
Dr.TDS. UBDTCE-DVG
71. (i) Two-group simple randomized design:
Population defined, sample randomly selected
Items randomly assigned to experimental and control groups
Design yields representative groups
Allows drawing conclusions applicable to population
Experimental and control groups receive different treatments
Common in behavioral sciences research
Simple design, randomizes sample differences
Doesn't control individual differences among those conducting treatments
Example: Comparing groups of students receiving different training
Individual differences among students randomized, but extraneous variables not
controlled
4/17/2024 71
Dr.TDS. UBDTCE-DVG
72. (ii) Random replications design:
Limitations of two-group randomized design addressed in random replications design
Random replications minimize effects of individual differences and extraneous
variables
Each repetition in random replication design is called a "replication"
Serves to control effects of extraneous variables and randomize individual
differences
Diagram illustrates two populations in replication design
Sample randomly selected and assigned to experimental and control groups
Equal number of items typically placed in each group to prevent size bias
Variables assumed to be randomly distributed among groups
Random replication design extends from two-group simple randomized design
4/17/2024 72
Dr.TDS. UBDTCE-DVG
74. 5. Randomized block design (R.B. design)
Randomized block design (R.B. design) improves upon C.R. design
Applies local control principle alongside other experimental principles
Subjects grouped into homogeneous blocks based on selected variable
Each block has same number of subjects as treatments
One subject randomly assigned to each treatment within block
Blocks fix extraneous factors to measure their impact on variability
Treatments evenly distributed within blocks
Analyzed using two-way ANOVA
Example: Five students from different IQ blocks given four forms of standardized
test in statistics
Randomized test order accounts for extraneous factors like fatigue or experience
gained from repeated testing
4/17/2024 74
Dr.TDS. UBDTCE-DVG
75. Four different forms of a standardised test in statistics
were given to each of five students (selected one from
each of the five I.Q. blocks) and following are the scores
which they obtained.
4/17/2024 75
Dr.TDS. UBDTCE-DVG
76. 6. Latin square design (L.S. design)
Commonly used in agricultural research
Addresses varying soil fertility and seed impact in experiments
Each fertilizer appears five times, once per row and column
Treatments allocated to plots to ensure no treatment repeats in any row or column
Blocks represented by rows and columns
Analysis similar to two-way ANOVA
Eliminates differences in fertility gradients, focusing on fertilizer effects
Limitation: Assumes no interaction between treatments and blocking factors
Can adjust means of rows and columns to address this limitation
Requires equal number of rows, columns, and treatments
Smaller designs like (2 × 2) lack degrees of freedom for analysis
Larger designs (5 × 5) to (9 × 9) commonly used to maintain homogeneity in rows
and columns

77. 7. Factorial designs:
Factorial designs explore effects of multiple factors
Two types: simple factorial and complex factorial designs
Simple factorial designs analyze two factors' effects
Examples include 2 × 2, 3 × 4, or 5 × 3 designs
Subjects randomly assigned to treatment conditions
Analysis examines main effects and interactions
Graphical representation illustrates interactions
Can involve one experimental and one control variable, or two of either
Example: Comparing class size and instruction technique in a 2 × 2 design
Another example: Comparing genders and seniority levels in a 2 × 2 design with
both variables as control factors
