Question
8: A researcher was interested in determining the effects of different types of drugs on problem solving. The researcher randomly assigned fifty participants to take a depressant, fifty participants to take a stimulant, and fifty participants to take a placebo (i.e., sugar pill). All of the participants were given an hour to complete a set of simple arithmetic problems. Higher scores on the test indicated that more answers were correct. Is there a difference in how many questions were correct on average between the groups? What statistical analysis would be used for this scenario ? 8: A researcher was interested in determining the effects of different types of drugs on problem solving.
