What is Validity? - ✔✔whether or not the results of the study were obtained

What is reliability? - ✔✔the quality of being trustworthy and believable
- results from expertise and experience

- can take findings from small sample size and apply to larger population
What is internal validity? - ✔✔- Knowing with certainty that it was the

*not confounding variables*

nothing
What is a Quasi-Experimental Study? - ✔✔- level 3
- the independent variable is manipulated but there *is no randomization or
control group*
- typically studies in which it would be unethical for a control group to be
included
3 Group RCT - ✔✔- intervention group
- attention control group that doesn't get intervention but gets everything
else
- control group gets nothing
- adding the attention control group helps isolate the independent variable
2-Group RCT with Posttest Only - ✔✔- intervention and control group
- not as strong because without the pretest there is no baseline data
2-Group RCT with repeated measures - ✔✔- intervention, control, baseline
data, then test scores and test again months later
