A researcher investigated whether reading comprehension was better when reading text on a digital screen compared to printed paper. The researcher used an independent groups design.
In Condition 1, participants were given 5 minutes to read a 500-word story on a digital tablet screen. They were then asked to complete a 10-item multiple-choice comprehension test about the story.
In Condition 2, participants were given 5 minutes to read the same 500-word story printed on paper. They were then asked to complete the same 10-item multiple-choice comprehension test.
Explain two reasons why it was more appropriate to use an independent groups design than a repeated measures design in this study.
