The combination of plasma and formed elements is called A) serum. B) lymph. C) whole blood. D) extracellular fluid. E) packed blood. Which of these is not one of the formed elements of blood? A) antibodies B) platelets C) RBCs D) lymphocytes E) basophils The ______ is a procedure that is used to determine the number of each of the various types of white blood cells. A) hematocrit B) complete blood count C) reticulocyte count D) differential count E) mean corpuscular volume The _______ is a procedure that is used to determine the number of mature erythrocytes. A) RBC count B) complete blood count C) reticulocyte count D) differential count E) platelet count _______ transport(s) oxygen and CO_2 in the RBCs. A) Ribosomes B) Mitochondria C) DNA D) Hemoglobin molecules E) Components of the cytoskeleton Solution 39) Plasma and formed elements together is wholly called as Blood. Formed elements are Red Blood Cells (RBC), White Blood Cells (WBC) and platelets. 40) Antibodies are not among the formed elements of blood because, antibodies are proteins that are produced to neutralize the bacteria and virus. Where as, lymphocytes and basophils are types of WBCs. 41) Differential count method is used for determining the number of different types of WBCs. 42) Reticulocyte count gives the number of mature erythrocyte count among the RBCs. 43) Haemoglobin molecules transports the oxygen and carbon dioxiode to the RBCs..

1. The correlation between a company's advertising independent variable) and sales (dependent
variable) was .96 for the data of the past 20 years. This proves that advertising was the cause of
sales.
true
false
During the course of an experiment in Madison, Wisconsin aimed at determining the effect of
"discount pricing" on good sales, Gisholt Machine Company which was one of the largest
employers in Madison closed its plant. This is an example of a maturation effect.
true
false
Students taking an achievement test for the second time usually do better than those taking the
test for the first time. This is an example of the:
history effect
maturation effect
interactive testing effect
main testing effect
selection bias effect
What are the two main ways in which the prior equality of comparison groups is established?
randomization and statistical regression
matching and randomization
turnover and analysis and cross sectional analysis
regression and smoothing
longitudinal analysis and cross sectional analysis
The factor that makes the data from true experimental designs more valid than data from any
preexperimental designs is:
matching
randomization
the absence of extraneous sources of error
the fact that the results can always be generalized to the larger population
the fact that each of the test units is measured before and after the introduction of the
experimental stimulus
The tendency of extreme cases of the phenomenon to deviate toward a more central position
during the course of an experiment refers to:
statistical regression
turnover analysis

2. instrument variation
the main testing effect
selection bias
The extraneous variable, instrument variation (or decay):
does not result from variation in administration of the interview
can be acute when there are multiple observers or interviewers
is not attributed to the facility with which the interviewer handles the assignment
does not occur if minor modification, such as a slight change in the wording of a specific
question so as to make it more understandable without changing its meaning, is made
does not occur with interviews conducted by the same interviewer
The type of study design that affords the researcher the most control is:
a field experiment
an exploratory design
a descriptive design
a laboratory experiment
a sample survey
The use of randomization to eliminate selection bias in experimental designs works best when
the groups being compared are small.
true
false
You have decided on a quasi-experimental design Time Series Analysis, which involves repeated
measurements over time. Which of the following statements is (are) true:
This is a longitudinal study
There is no separate control group
Control over the extraneous variation (experimental biases) is accomplished via statistical
analysis rather than the Control group
All of the above
None of the above
When referring to the question of whether the experimental stimulus made some difference in the
specific instance under investigation, one is referring to:
external validity
internal validity
concomitant variation
cross sectional analysis

3. interaction errors
When referring to the question as to what populations and settings can the observed effect be
generalized, one is referring to:
concomitant variation
turnover analysis
external validity
longitudinal analysis
cross-sectional analysis
Select the question that can be answered through experimentation:
Do children from upper classes drink more carbonated beverages than those from lower classes?
Will Shell gasoline with platformate provide better mileage than Shell without platformate?
Does the average male use cosmetic?
Is the standard of living higher than ten years ago?
none of the questions can be answered by experimentation
In the BeforeAfter design with Control Group the control group difference (04 03 ) reflects:
the effects of the extraneous influences
the difference between the control group and the experimental group
the change in attitude of subject
the interactive effect of testing
the effect of the experimental stimulus
A single group of test units is exposed to an experimental variable and then is observed once for
their response. This is what type of study?
a one group pretestposttest study
a postexperimental study
a static group comparison
a oneshot case study
a longitudinal study
The typical sequence of Exploratory-to-Descriptive research is sometimes followed by an
Exploratory research in order to:
Spend the remaining money, so the budgets for future studies are not cut
Prepare the “beachhead” for the next study
Impress the management
Use the “respondents” to clarify the results of the descriptive study
None of the above
The difference between the Main Testing Effect and the Interactive Testing Effect is that
Interactive testing effect involves the “treatment” variable

4. Main Testing Effect is more damaging
Main testing Effect occurs in the experimental group and the Interactive Testing Effect in the
Control group
All of the above
None of the above
In the “Before-After withControl Group” design, the Control groups allows for:
Control of the Main Testing Effect
Control of the Interactive Testing Effect
Control of both, the Interactive and the Main Testing Effect
Use of a control group controls for neither, the Interactive and the Main Testing Effect
The name of the design to be a misnomer, there is no Control group as such
Selecting respondents who hold a very favorable attitude for a study of the effect of a
promotional campaign on consumer attitudes is an example of "statistical regression."
true
false
A sample of those Wisconsin students who held the most extreme views (positive and negative)
on coeducational dorms was selected for intensive interviewing for their reasons why. Upon
repeated questioning, the students tended to convey moderate views on the question. This is an
example of statistical regression.
true
false
A researcher investigating the impact of television advertising on consumer attitudes toward
Brand X, compared with attitudes of a sample of respondents who did not watch the ABC
Sunday Night Movie (one of the sponsors of which was Brand X) against those who did. This is
an example of:
statistical regression
history
the interactive testing effect
selection bias
the main testing effect
Researcher decided to use a Before-After with Control Group Design, to test the impact of an
add on the attitudes toward a brand A. In order to decrease the potential interactive testing effect
the researcher decided to use many brands, without realizing that this may increase the:
Main Testing effect
Mortality Effect
Maturation Effect

5. Main Instrument Variation
Another effect starting with an “M” which I can not recall, at the moment
Solution
1)
true
2)
true
3)
interactive testing effect
4)
regression and smoothing
5)
the fact that each of the test units is measured before and after the introduction of the
experimental stimulus
