A-B-A
baseline, intervention, baseline
A-B-A-B

mixed design
combines within-subjects and between-subjects design (two groups, two interventions)
within subjects
participants experience all conditions (one group, two interventions)
between subjects
participants experience some conditions (randomly assigned) (two groups, one interventions)
treatment-as-usual group

waiting-list control group
participants who don’t receive treatment until after the study
correlation design
examines the relationship between two or more variables without manipulating them
experimenter-expectancy effect/expectancy bias/experimenter effect
when a bias causes researchers to unconsciously influence the participant
double-blind procedure
both researchers and participants are blind the the thesis
single-blind procedure
participants are blind but researchers aren’t
ecological validity
the extent to which experimental findings can be generalized to real-life situations
external validity
the extent to which you can generalize the findings of a study to other situations
reliability
consistency
ANOVA
a statistical analysis test that tests for differences between two or more IV’s
mixed design ANOVA
compares the mean differences between groups that have been split on two “factors”
factorial design ANOVA
any ANOVA that uses more than one categorical independent variable
repeated design ANOVA
tests whether there are statistically significant differences in three or more dependent samples
