Consider the following scenario: a pro-life group wanted to test the effectiveness of an anti-abortion commercial. Two random samples, each of 250 respondents, were recruited in Atlanta. One group was shown the anti-abortion commercial. Then attitudes toward abortion were measured from respondents in both groups:
- Identify the independent and dependent variables in this experiment.
- Identify what type of research design was used.
- Identify potential threats to internal and external validity in this experiment.
- If the respondents had been chosen by convenience, rather than randomly, what type of research design would result?
