- Hawthorne effect
- external validity
- criterion-related evidence
- a refers to the change in performance caused by the mere presence of others watching.
- b random selection, random assignment
- c the technique of equating groups on one or more variables, with the result that each member of one group has a direct counterpart in another group
- d is used to determine validity by comparing the instrument used in the study with another instrument or form of assessment presumed to measure the same variable. Two forms of criterion-related validity are predictive and concurrent.
- e generalizability
5 Multiple choice questions
- focuses on specifying a problem and creating an action plan to address the problem
- includes a variety of different types of evidence supporting the characteristic being measured. Three common ways to measure construct-related validity include using a clearly defined variable, hypotheses based on theory to explain the variable, and logical and empirically tested hypotheses.
- a statistical procedure for examining the results of several research studies on the same topic and determining the congruence and divergence of outcome data
- control group
- double blind study
5 True/False questions
statistical regression → researchers manipulate variables or introduce a treatment to one participant or group over time and intently study effects
nonexperimental design → used to describe participant characteristics or behaviors and do not involve the application of any treatment to participants
single-case design → can be used to make cause-effect determinations
instrumentation: → consistency and reliability
Methods of Control: → randomization
using participants as their own controls
analysis of covariance
