11. _________ the extent to which a particular treatment in : 1260329.
11. _________ is the extent to which a particular treatment in an experiment produced the sole effect on the dependent variable.
A) external validity
B) internal validity
C) nomological validity
D) extraneous
12. __________ refers to the extent the findings of an experiment (or research study) can be generalized to the population as whole or to the specific population being studied.
A) external validity
B) internal validity
C) nomological validity
D) extraneous
13. Testing effects occur when subjects become sensitized to the measurement instrument or experiment through the pre-test in a way that affects the results of the experiment.
A) maturation
B) instrumentation
C) testing effects
D) selection effect
14. __________ is caused by a change in the measurement instrument, its calibration, or other procedures used to measure the dependent variable.
A) maturation
B) instrumentation
C) testing effects
D) selection effect
15. __________ occurs when the sample selected for a study is not representative of the population being studied or the samples selected for different groups within the study are not statistically the same. If the study sample is not representative of the population being studied, then external validity is threatened since the results of the experiment cannot be generalized to the population.
A) maturation
B) instrumentation
C) testing effects
D) selection effect

A) pre-experimental designs
