F10 1200 912 Open Questions The following requires using Chi square. A study of the effects of lack of REM sleep on the ability to recall a list of words found that of participants who did not get normal REM sleep. Recall REM Sleep Quality Normal Deprived Total High 14 Moderate 62 16 Low 10 Total 20 20 40 A. Using the values shown, find the expected (E) values for each cell, and put them in Table1. Here are the values that were actually observed: REM Sleep Quality Recall Normal Deprived Total High 10 4 14 Moderate 9 7 16 Low 1 9 10 Total 20 20 40 B. With these observed values, calculate Chi-square. E=19-3 20 C. Find the degrees of freedom and determine if your chi-square is significant
