1 pts D Question 8 Dr. Apnea conducted a study investigating the effects of sleep deprivation on complex problem solving. He gave 25 college students a problem solving test at noon on one day and a second problem solving test at noon the following day. He found that there was a statistically significant mean decrease of 4.7 between the two tests from the first day to the second day. The test yielded a Cohen's d-82 Which of the following statements is an accurate interpretation of Dr. Apnea's r esearch? O If you don't your problem solving abilities suffer with a medium absolute magnitude. If you don't get enough sleep your problem solving abilities suffer, but only with a small absolute magnitude. It doesn't matter how much sleep you get, some people just aren't good at problem solving If you don't get enough sleep your problem solving abilities suffer with a large absolute magnitude. O O No new data to save. Last checked at 6:38pm Submit Quiz

Explanation / Answer

Cohen d says that If d=0.2 there is no difference

If d=0.5 then the difference is moderate

If d=0.8 then there is strong difference.

Here d=0.82 so there is significant difference between the two means

Hence option D is correct
