โ weakness of true experiments. Answer: 1. results in controlled setting may not translate to real life
โ experimental mortality/ attrition. Answer: subjects drop out of study early; pretest โ regression towards the mean. Answer: populations with extreme values will tend to retest with less extreme values; randomization โ history. Answer: an event happens that impacts results; control group โ maturation. Answer: people change over time and grow; control group โ testing effect. Answer: the process of testing creates a change in the dependent variable (common with knowledge tests); mutliple groups et. solomon four group design โ solomon four group design. Answer: two treatment and two control groups, only one set of T and C groups get the pre test โ diffusion/contamination. Answer: control gets the intervention when they shouldn't, often groups share information with one another; try to anticipate and measure it โ What do you need for causality (internal validity)?.
