Chapter Self-Test


This activity contains 6 questions.

	A study in which the attitudes of boys and girls in the rural US are compared to the attitudes of boys and girls from the urban US would not be called an experiment because   children could not be randomly assigned to gender. there is no independent variable that is manipulated by the researcher. the data would come from self-reports rather than objective tests. the research hypotheses would probably not be directional.

	The structure by which variables are arranged in an experiment is called the   experimental design. causal-comparative grid. variable grid. factor structure.

	An experimental design in which changes in the dependent variable can be unambiguously attributed to changes in the independent variable is said to have   experimental reliability. statistical conclusion validity. investigative validity. internal validity.

	External validity has to do with   the credibility of experimental results to external audiences. the extent to which experimental results can be generalized. the outside appearance of experimental results. the control of extraneous variables.

	A posttest-only control group design with random assignment to groups is still susceptible to which threat to internal validity?   experimental mortality history statistical regression maturation

	Which combination below could not occur for an experiment?   high internal validity – low external validity low internal validity – high external validity low internal validity – low external validity high internal validity – high external validity
