RSCH 202 MODULE 4 Quiz 1 (EMBRY)

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. Cause-and-effect inferences can be contaminated by the effects of the passage of time. Such contamination effects are denoted history effects.
3. External validity of lab experiments refers to the confidence we place in the cause-and-effect relationship.
4. A Quasi-Experimental Design guarantees the maximum internal and external validity, ruling out many other rival hypotheses.
5. 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.
6. One way of controlling “nuisance” variables is to match the various groups by picking the confounding characteristics and deliberately spreading them across groups.
7. 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.
8. 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.
9. 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.
10. History effects (the dropout of individuals from groups) is a problem for all experimental designs.
11. A Quasi-Experimental Design guarantees the maximum internal and external validity, ruling out many other rival hypotheses.
12. Operationalizing is making a variable measurable.
13. Operationalizing precedes the definition of a concept.
14. Biases that might affect the internal validity of experimental designs are often reduced by enhancing the level of sophistication of the experimental design.
15. Internal validity refers to the extent of generalizability of the results of a causal study to other settings.
