Question

Researchers wanted to study the relationship between pizza consumption by college freshmen and academic achievement. The researchers selected a freshmen history class with 900 students. The class lasted for 16 weeks and had weekly quizzes.

The researchers used random sampling and got two equivalent groups of participants from the class. Each group had 35 students. One group was the pizza group and one was the non-pizza group. To prepare for the experiment, the researchers compared the average quiz results of both groups for the first three weeks of the course and found no statistically significant difference between quiz scores.

In weeks 4 - 12, the researchers provided pizza dinner for everyone in the pizza group but those in the non-pizza group were told not to eat pizza 48 hours before the weekly quizzes. After week 12, the researchers compared the average quiz scores in each group and found that the non-pizza group had a statistically higher average quiz score than the pizza group. The researchers concluded that pizza consumption hinders academic performance of college freshmen.

Read the example scenario provided in the overview and then critically evaluate it using the four basic critical questions

* What is the claim?

*How good is the evidence?

*What other information is relevant?

*Are relevant fallacies avoided?
