RSCH 202 MODULE 4 Quiz (EMBRY)

Chapter 10 and 11 for MOD 4 TEST

1. One way of controlling “nuisance” variables is to match the various groups by picking the confounding characteristics and deliberately spreading them across groups.
2. A Quasi-Experimental Design measures true cause-and-effect relationships.
3. The construct ‘hunger’ is a typical example of a construct that must be operationalized because it is an abstract and subjective concept.
4. A time series design thus allows the researcher to assess the impact of a treatment over time.
5. A key problem of time series is history: certain events or factors that have an impact on the independent variable-dependent variable relationship might unexpectedly occur while the experiment is in progress.
6. Quasi-Experimental Designs expose an experimental group to a treatment and measure its effects.
7. Cause-and-effect inferences can be contaminated by the effects of the passage of time. Such contamination effects are denoted history effects.
8. The manipulation of the independent variable is also known as the treatment, and the results of the treatment are called treatment effects.
9. Biases that might affect the internal validity of experimental designs are often reduced by enhancing the level of sophistication of the experimental design.
10. History effects (the dropout of individuals from groups) is a problem for all experimental designs.
11. Which of the following answers is a ‘concept’?
12. Which of the following are benefits of randomly selecting subjects for an experiment?
13. Which of the following might affect the external validity of an experiment?
14. What is the operationalization of a variable?
15. Suppose you want to operationalize “achievement motivation.” Which of the following would probably not be an attribute of someone who is “achievement motivated”? 

New Questions from 2nd Attempt:

1. Operationalizing is making a variable measurable.
2. An interactive testing effect occurs when the prior observation (the pretest) affects the later observation (the posttest).
3. A field experiment is an experiment done in the natural environment in which work goes on as usual, but treatments are given to one or more groups.
4. External validity of lab experiments refers to the confidence we place in the cause-and-effect relationship.
5. Major threats to validity in a “pretest & posttest with one experimental group only” are:
6. Which of the following is not part of operationalization of a concept?
7. Operationalization means:

New Questions from 3rd Attempt:

1. The operationalization of a construct means that there must be looked for as many related correlations, dimensions and elements of the construct as possible.
2. Operationalizing precedes the definition of a concept.
3. There is a trade-off between internal validity and external validity. If we want high internal validity, we should be willing to settle for lower external validity and vice versa.
4. A Quasi-Experimental Design guarantees the maximum internal and external validity, ruling out many other rival hypotheses.
5. Internal validity refers to the extent of generalizability of the results of a causal study to other settings.
6. The manipulation of the independent variable is also known as the treatment, and the results of the treatment are called treatment effects.
7. A Quasi-Experimental Design measures true cause-and-effect relationships.
