Usually, you'll run this analysis on values placed on a Column table, and these choices won't be available. But if you enter data on a grouped table with subcolumns, Prism gives you three choices: To analyze each subcolumn separately, to average the values in the subcolumns on each row and then analyze that stack of means, or to treat all the values as one sample of data (paying no attention to which row any values are on).
Enter a value for alpha, the threshold P value to define statistical signficance.
Choose P value format and number of digits to use when displaying results.
