Define repeated measures design (within subject) |
the dependent variable is measured 2+ times for each individual in a single sample. |
|
|
Define matched-subjects design |
each individual in one sample is matched with an individual in the other sample. The matching is done so that the two individuals are equivalent with respect to a specific variable that the researcher would like to control. |
|
|
What does variability mean in a treatment effect for a repeated-measures study? |
It describes the consistency of the treatment effect. |
|
|
Repeated-measures versus independent-measure design |
1. Number of subjects: RM requires fewer subjects. 2. Study changes over time- RM can show changes over time. 3. Individual differences-RM reduces ind. differences that might exist when using different participants in an independent-measures test. |
|
|
What is one way to deal with time-related factors and order effects in repeated-measure tests? |
Counterbalancing. The sample is divided into two groups, where sample group one does train one, then two, and sample group two does two, then one, so the practice effects are accounted for. |
|
|
Assumptions of the related-samples t test |
1. The observations within each treatment condition must be independent. 2. The population distribution of difference scores (D values) must be normal. |
