Question

D Question 8 1 pts 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 research? O If you don't get enough sleep your problem solving abilities suffer with a medium absolute magnitude. O If you don't get enough sleep your problem solving abilities suffer, but only with a small absolute magnitude. O It doesn't matter how much sleep you get, some people just aren't good at problem solving. O If you don't get enough sleep your problem solving abilities suffer with a large absolute magnitude. No new data to save. Last checked at 6:21pm Submit Quiz

Explanation / Answer

Since cohen's d= 0.82 which represents  a 'large' effect size. So if you don't get enough sleep your problem solving abilities suffer with a large absolute magnitude.
