p-value for highlighting The default p-value for highlighting is .05. You can adjust this p-value by entering a new value in the text box or using the microscrolls. On the spreadsheets for Multiple comparisons of mean ranks for all groups, STATISTICA will highlight all p-values that are equal to or less than the value specified in this field. For more details on p-value, see Elementary Concepts.
