Flashcards in Chapter 13 Deck (11):
1

cross-sectional comparison

comparisons to see if both comparisons lead to the same conclusion (comparing different points in time)

2

interrupted time-series design

introducing the stimulus during the period of assessment over time in order to evaluate its effect on the variables

3

matching

problem is that even if matched on pre-test, impossible to determine pre-existing group differences

4

one-group pretest-posttest design

based on within-individual treatment comparisons, treatment effect is average difference between pre+post test

5

panel design

"the same families were reinterviewed regularly" // possible to document variations

6

pretest-posttest nonequivalent control group design

same as static design, but each group is given pre+post test to measure dependent variable at multiple points in time

7

quasi-experimental designs

when one or more independent variables are manipulated but participants are not randomly assigned to levels of the manipulated variables

8

regression toward the mean

ahen the experimental manipulation is applied to groups of people, who are extreme on the variable of interest, and who subsequently tend to regress toward the mean

9

replicated interrupted time-series design

comparisons between treatment and control conditions can be made both within the same participants over time and between diff groups of participants over time

10

static-group comparison design

assignment by naturally occurring groups X or self-selection

11

undermatching

matching on variables known to be associated with the dependent variable fails because you can't know if you matched on enough variables to represent the population
