Validity and Reliability Practice Name___________________________ Date_____________ Period__

1. On a scale of 1-5, how would you rate the internal validity of the experiment? What is you rationale?Consider: What research method is being used? How many controls are present? What measures are taken against experimenter bias? What types of confounding variables are accounted for/not accounted for? What demand characteristics may be present? What data was collected, and how was it interpreted? Is there any possible observer bias? Is it possible that the study is too reductionist?

2. On a scale of 1-5, how would you rate the external validity of the experiment? What is your rationale?Consider: What is the ecological validity of the experiment? Is the sample representative of the population? Was there ethnocentric bias? Was there a gender bias? How was the sample gathered? Would the findings be generalizable?

3. On a scale of 1-5, how would you rate the internal reliability of the experiment? What is your rationale?Consider: What research method is used? How standardized are the procedures? What time(s) was the study done? How many measures of behavior were tested?

4. On a scale of 1-5, how would you rate the external reliability? What is your rationale?Consider: Would the study be able to be replicated? Did they complete a inter-rater reliability test or a split-half test or a test-retest if applicable? Were the results from experiment 1 similar to experiment 2?
