Question

Dr. Dormeur studies sleep and sleep disorders. She is curious as to whether technology exposure before bedtime causes people to fall asleep more slowly. She recruits a sample of 60 middle-aged women from a local church who reported no history of sleep problems. She creates two conditions. All participants come to the sleep lab for two nights in a row and experience both conditions. In the first condition (A), participants were asked to play an online game (Candy Crush) on an iPad for 10 minutes prior to going to bed. In the second condition (B), participants were asked to read a newspaper article about the inventor of Candy Crush, which took about 10 minutes to read, prior to going to bed. With the use of an electroencephalograph (EEG), Dr. Dormeur measures how long it takes participants to fall asleep.

Dr. Dormeur should analyze her data using a:

Select one:

one-way between-subjects ANOVA.

chi-square test.

simple linear regression.

repeated-measures t-test.

Answer 1

here since subjects are same in both groups

therefore correct option is repeated-measures t-test.

(since subject is being repeated in both the groups)
