# A researcher wants to know whether a hard copy of a textbook...

A researcher wants to know whether a hard copy of a textbook provides additional benefits over an e-book. She conducts a study where participants are randomly assigned to read a passage either on a piece of paper or on a computer screen. After a distractor task lasting 30 minutes, the participants are tested for their comprehension of the passage with a multiple-choice test containing 10 questions about their passage. Comprehension was scored using percent correct (0 â€" 100%). The researcher predicts that those randomly assigned to read the passage on a piece of paper will remember significantly more than those who read the passage online. Question: What is the most appropriate statistical test to conduct given this scenario?

Independent samples t-test

Correlated groups t-test

Pearsonâ€™s r correlation

Phi correlation
