ANOVA, CHI-SQUARE AND NONPARAMETRIC TESTS Contingency tables: Expected frequencies Keira The following contingency table gives a summary of the data from 2000 trials of a visual experiment. Each of the trials was performed by either a colorblind participant or a non-colorblind participant. Each trial resulted in a "hit, a miss," a "alse alarm," or a "correct rejection. In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks...
