Scientific Research


       Scientific research is a systematic, controlled,
        empirical, and critical investigation of natural
        phenomena guided by theory and hypotheses
        about the presumed relations among such
        phenomena.

Paradigm of Inquiry in Scientific Approach

    1.   Problem-Obstacle-Idea – involves getting the idea out in
         the open and expressing the problem in some reasonably
         manageable form
    2.   Hypothesis - a conjectural statement, a tentative
         proposition about the relation between two or more
         phenomena or variables
    3.   Reasoning-Deduction - the scientist deduces the
         consequences of the hypothesis he has formulated
    4.   Observation-Test-Experiment - is only part of the
         scientific enterprise. If the problem has been well stated,
         the hypothesis or hypotheses adequately formulated, and
         the implications of the hypotheses carefully deduced, this
         step is almost automatic assuming that the investigator is
         technically competent.

Classification of Research

       Research as a formal, systematic and intensive
        process of scientific investigation is always
        directed toward the solution of a problem

        Basic Research - it develops or enhances theories

        Applied research - it tests theories and evaluate
        their usefulness in solving actual problem
        situations in order to improve a product or
        process.

        Action Research - Applied research which is
        focused on immediate application.

Selecting a Research Problem


        Analyzing the research problem.
        Identifying the variable.
        Stating the problem.
        Evaluating the problem.
        Setting up of a sub-problem.

14                    Erlinda P. Villamoran
Criteria of Problems and Problem
     Statement
     1.   The problem should express a relation between
          two or more variables. It asks, in effect, questions
          like is A related to B? How are A and B related to
          C? How is A related to B under conditions C and
          D?

     2.   The problem should be stated clearly and
          unambiguously in question form. Instead of saying
          for instance, “The problem is . . . ,” or “The
          purpose of this study is …,” ask a question.

     3.   The problem and the problem statement should be
          such as to imply possibilities of empirical testing
15                        Erlinda P. Villamoran
Significance of the Study

        Rational, timeliness and/or relevance of the
         study should be clearly stated;
        Contribution to the accumulation of
         knowledge, or to filling up a knowledge or gap;
        Contribution to building, validating or refining
         prevailing theories;
        Contribution to meeting a pressing need of a
         specific group like solving a problem or
         improving certain conditions; possible
         implications and;
        Contribution to refining concepts, improving
         research instrumentation and methodologies.
16                     Erlinda P. Villamoran
Scope/Limitations of the Study
        Scope defines the coverage or boundary of the
         study in terms of the area or locality and
         subjects or population covered, the duration
         or period of the study and the research issues
         are focused.

        Limitations are statements which alert the
         reader of the research report to certain
         constraints over which the researcher has no
         control. It also defines the conditions beyond
         the control of the researcher that may place
         restrictions on the conclusions of the study
         and their application or other situations.
17                     Erlinda P. Villamoran
Theoretical Framework
     Relevant Theory

        A theory is a set of interrelated constructs
         (concepts), definitions and propositions that present
         a systematic view of phenomena by specifying
         relations among variables, with the purpose of
         explaining and predicting the phenomena

        Sources of theories:
          – Research literature and the conceptual writings in
            a discipline
          – If a theory did exist or was not well developed,
            one could conceptualize a theory based on a
            logical analysis of prior research applied to the
            phenomenon under study.
18                       Erlinda P. Villamoran
Theoretical Framework
     Role of Theory in Research

     1.   Provides a framework by serving as the point
          departure for the pursuit of a research
          problem
     2.   The theory identifies the crucial factors
     3.   It provides a guide for systematizing and
          interrelating the various facets of the
          research.
     4.   It helps identify gaps and weak points
     5.   Theory may light the way for continued
          research on the phenomena under study

19                    Erlinda P. Villamoran
Theoretical Framework
     Related Literature and Studies
        Involves the systematic identification, location
         and analysis of documents containing
         information on the research problem
        Literature refers to the writings of a country or
         books dealing with a special subject valued as
         works of arts like drama, fiction, essays, ..
         etc.”, therefore all written material or article
         can be called as literature.
        Related studies are investigations that are
         usually published materials like manuscript,
         theses, and dissertations which are conducted
         previously to which the present study had
         similarity and relatedness.
20                     Erlinda P. Villamoran
Conceptual Framework / Variables

        Conceptual Framework - presents the
         relationship between the different specific
         constructs that we want to study. A construct
         is a clearly defined concept.

        Variable is a characteristic that has two or
         more mutually exclusive values or properties.

         1.   Dependent Variable (DV)
         2.   Independent Variable (IV)
         3.   Moderator Variable
         4.   Control Variable

Hypothesis
        Hypothesis comes from the Greek prefix “Hypo”
         meaning beneath or underlying, and the Greek word
         “thesis” meaning a proportion or statement that can
         be supported by argument or evidence.

        It is a conjectural statement of the significant
         relationship between two or more variables. It is still
         doubtful and needs to be tested.

         Two types of hypothesis:
         1. Null hypothesis
         2. The alternative or experimental or research
            hypothesis
            a. Non-directional Hypothesis

Data Processing

         Is a means of converting information either manually or by
          machine. This involves the following phases:

     1.   Data Coding . It is a process of grouping the response to a
          question into categories and assigning numbers, characters,
          and/or other symbols called codes.

     2.   Selecting Appropriate Statistical Method

          Factors to be considered:
          a. Variables – a noun that stands for variation within a class of
             objects.
          b. Relationship of Variables – a statement about variables; two or
             more groups are compared or relationships among variables
             are studied within one group
          c. Measurement of Scales
          d. Sample Size

     Ordinal        Ranks data; uses numbers only to
                    indicate ranking
     Interval       Assumes the difference between
                    scores of equal magnitude really
                    mean equal differences in the variable
                    measured; (actual number)
     Ratio          All of the above, plus true zero point
32                  Erlinda P. Villamoran

    Scientific Research  Scientific research is a systematic, controlled, empirical, and critical investigation of natural phenomena guided by theory and hypotheses about the presumed relations among such phenomena. 4 Erlinda P. Villamoran
  • 5.
    Paradigm of Inquiryin Scientific Approach 1. Problem-Obstacle-Idea – involves getting the idea out in the open and expressing the problem in some reasonably manageable form 2. Hypothesis - a conjectural statement, a tentative proposition about the relation between two or more phenomena or variables 3. Reasoning-Deduction - the scientist deduces the consequences of the hypothesis he has formulated 4. Observation-Test-Experiment - is only part of the scientific enterprise. If the problem has been well stated, the hypothesis or hypotheses adequately formulated, and the implications of the hypotheses carefully deduced, this step is almost automatic assuming that the investigator is technically competent. 5 Erlinda P. Villamoran

    Classification of Research  Research as a formal, systematic and intensive process of scientific investigation is always directed toward the solution of a problem Basic Research - it develops or enhances theories Applied research - it tests theories and evaluate their usefulness in solving actual problem situations in order to improve a product or process. Action Research - Applied research which is focused on immediate application. 9 Erlinda P. Villamoran
  • 10.
    Sources of aResearch Problem  Experience and observations.  The vast amount of literature in your own field.  Courses that you have taken.  Journals, books, magazines, or abstracts.  Theses and Dissertation.  Your Professor and Your Classmates. 10 Erlinda P. Villamoran
  • 11.
    Elements of aResearch Problem  Aim or purpose of the problem for investigation.  The subject matter or topic to be investigated.  The place or locale where the research is to be conducted.  The period or time of study during which data are to be gathered.  Population or universe from whom data are to be collected. 11 Erlinda P. Villamoran
  • 12.
    Criteria in theSelection of a Research Problem  Novelty and avoidance of unnecessary duplication.  Significance for the field represented and implementation.  Interest, intellectual, curiosity, and drive.  Sponsorship and administrative cooperation.  Cost and returns.  Time factor.  Training and personal qualification.  Availability of data or method.  Special equipment and working conditions. 12 Erlinda P. Villamoran
  • 13.
    Guidelines in theSelection of a Research Problem  The research problem or topic must be chosen by the researcher himself.  It must be within the interest of the researcher.  It must be within the specification of the researcher.  It must be within the competence of the researcher to tackle.  It must be within the ability of the researcher to finance.  It is researchable and manageable. 13 Erlinda P. Villamoran
  • 14.
    Selecting a ResearchProblem  Analyzing the research problem.  Identifying the variable.  Stating the problem.  Evaluating the problem.  Setting up of a sub-problem.  Presentation of the problem. 14 Erlinda P. Villamoran
  • 15.
    Criteria of Problemsand Problem Statement 1. The problem should express a relation between two or more variables. It asks, in effect, questions like is A related to B? How are A and B related to C? How is A related to B under conditions C and D? 2. The problem should be stated clearly and unambiguously in question form. Instead of saying for instance, “The problem is . . . ,” or “The purpose of this study is …,” ask a question. 3. The problem and the problem statement should be such as to imply possibilities of empirical testing 15 Erlinda P. Villamoran
  • 16.
    Significance of theStudy  Rational, timeliness and/or relevance of the study should be clearly stated;  Contribution to the accumulation of knowledge, or to filling up a knowledge or gap;  Contribution to building, validating or refining prevailing theories;  Contribution to meeting a pressing need of a specific group like solving a problem or improving certain conditions; possible implications and;  Contribution to refining concepts, improving research instrumentation and methodologies. 16 Erlinda P. Villamoran
  • 17.
    Scope/Limitations of theStudy  Scope defines the coverage or boundary of the study in terms of the area or locality and subjects or population covered, the duration or period of the study and the research issues are focused.  Limitations are statements which alert the reader of the research report to certain constraints over which the researcher has no control. It also defines the conditions beyond the control of the researcher that may place restrictions on the conclusions of the study and their application or other situations. 17 Erlinda P. Villamoran
  • 18.
    Theoretical Framework Relevant Theory  A theory is a set of interrelated constructs (concepts), definitions and propositions that present a systematic view of phenomena by specifying relations among variables, with the purpose of explaining and predicting the phenomena  Sources of theories: – Research literature and the conceptual writings in a discipline – If a theory did exist or was not well developed, one could conceptualize a theory based on a logical analysis of prior research applied to the phenomenon under study. 18 Erlinda P. Villamoran
  • 19.
    Theoretical Framework Role of Theory in Research 1. Provides a framework by serving as the point departure for the pursuit of a research problem 2. The theory identifies the crucial factors 3. It provides a guide for systematizing and interrelating the various facets of the research. 4. It helps identify gaps and weak points 5. Theory may light the way for continued research on the phenomena under study 19 Erlinda P. Villamoran
  • 20.
    Theoretical Framework Related Literature and Studies  Involves the systematic identification, location and analysis of documents containing information on the research problem  Literature refers to the writings of a country or books dealing with a special subject valued as works of arts like drama, fiction, essays, .. etc.”, therefore all written material or article can be called as literature.  Related studies are investigations that are usually published materials like manuscript, theses, and dissertations which are conducted previously to which the present study had similarity and relatedness. 20 Erlinda P. Villamoran
  • 21.
    Conceptual Framework /Variables  Conceptual Framework - presents the relationship between the different specific constructs that we want to study. A construct is a clearly defined concept.  Variable is a characteristic that has two or more mutually exclusive values or properties. 1. Dependent Variable (DV) 2. Independent Variable (IV) 3. Moderator Variable 4. Control Variable 5. Intervening Variable 21 Erlinda P. Villamoran

    Hypothesis  Hypothesis comes from the Greek prefix “Hypo” meaning beneath or underlying, and the Greek word “thesis” meaning a proportion or statement that can be supported by argument or evidence.  It is a conjectural statement of the significant relationship between two or more variables. It is still doubtful and needs to be tested.  Two types of hypothesis: 1. Null hypothesis 2. The alternative or experimental or research hypothesis a. Non-directional Hypothesis b. Directional Hypothesis 27 Erlinda P. Villamoran
  • 28.
    Functions of Hypothesis 1. Helps the researcher determine what kind of research is to be done and what methodology may be used; 2. Means of stating assumptions and presenting or providing explanations; 3. Serves as determinations of the relevancy of facts; 4. Aids the researcher present the conclusions of the study; and 5. Provides format for the presentation, analysis and interpretation of research data. 6. Sources for the formulation of new hypothesis. 7. Provides the link between theory and observation; 28 Erlinda P. Villamoran

    Data Processing  Is a means of converting information either manually or by machine. This involves the following phases: 1. Data Coding . It is a process of grouping the response to a question into categories and assigning numbers, characters, and/or other symbols called codes. 2. Selecting Appropriate Statistical Method Factors to be considered: a. Variables – a noun that stands for variation within a class of objects. b. Relationship of Variables – a statement about variables; two or more groups are compared or relationships among variables are studied within one group c. Measurement of Scales d. Sample Size 31 Erlinda P. Villamoran
  • 32.
    Measurement Scales Measurement Characteristics of Scales Nominal Groups and labels data only, report frequencies or percentages Ordinal Ranks data; uses numbers only to indicate ranking Interval Assumes the difference between scores of equal magnitude really mean equal differences in the variable measured; (actual number) Ratio All of the above, plus true zero point 32 Erlinda P. Villamoran
  • 33.
    Commonly Used StatisticalAnalyses  Descriptive Statistics - one (1) variable at a time: 1. Measure of Central Tendency (mean, median, mode) 2. Measure of variability/dispersion (range, IQR, Standard Deviation, Quartile Deviation, Average Deviation, Coefficient of Variation)  Descriptive Statistics - two (2) variables at a time: 1. Measures of Correlation a. Pearson – for 2 sets of interval data b. Spearman rho – ordinal – ordinal (easier to compute) c. Kendall Tau – ordinal – ordinal (reliable for large n) d. Kendall Partial Correlation Coefficient – 3 sets of ordinal data e. Point Biserial – nominal – interval data 2. Measures of Association (Q coefficient, phi coefficient) 33 Erlinda P. Villamoran
  • 34.
    Commonly Used StatisticalAnalyses  Inferential Statistics - Used in hypothesis testing 1. Parametric (t-test) 2. Non – Parametric (Mc Nemar, Chi- square, Wilcoxon, Mann Whitney)  Analysis of Variance (ANOVA) – comparing more than 2 groups  Analysis of Covariance (ANCOVA) – for equating groups 34 Erlinda P.
