One way of controlling "nuisance" variables is to match the various groups by picking the confounding characteristics and deliberately spreading them across groups. True False A Quasi-Experimental Design measures true cause-and-effect relationships. True False The construct 'hunger' is a typical example of a construct that must be operationalized because it is an abstract and subjective concept. True False A time series design thus allows the researcher to assess the impact of a treatment over time. True False 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. True
False Quasi-Experimental Designs expose an experimental group to a treatment and measure its effects. True False Cause-and-effect inferences can be contaminated by the effects of the passage of time. Such contamination effects are denoted history effects. True False The manipulation of the independent variable is also known as the treatment, and the results of the treatment are called treatment effects. True False Biases that might affect the internal validity of experimental designs are often reduced by enhancing the level of sophistication of the experimental design. True False History effects (the dropout of individuals from groups) is a problem for all experimental designs. True False Which of the following answers is a 'concept'? Office. Plant. Job satisfaction. These are all examples of 'concepts'. Which of the following are benefits of randomly selecting subjects for an experiment? Controlling nuisance variables. Controlling statistical regression effects. Controlling selection bias effects. All of the above. Which of the following might affect the external validity of an experiment? History.
Interactive Testing. Instrumentation. Mortality. What is the operationalization of a variable? The definition of a variable. An overview of the subcomponents of a variable. The characteristics of a variable about which consensus exists between theoreticians. The way in which variables are rendered measurable.
Suppose you want to operationalize “achievement motivation.” Which of the following would probably not be an attribute of someone who is “achievement motivated”? Driven by work. Prefer to work on their own. Want to take on excessively challenging jobs. Want feedback from colleagues. Operationalizing is making a variable measurable. True False An interactive testing effect occurs when the prior observation (the pretest) affects the later observation (the posttest). True False
