When you run the District Summary Report, the mean RIT, median RIT, standard deviation, and goal means are missing.
This data will not be displayed if Small Group Display is not selected, and you have a group of less than 10 students. Additionally, if there is only 1 student in the grade, standard deviation fields cannot be calculated and will be blank.
Due to statistical unreliability, summary data for groups of 10 or fewer students are typically not shown. When generating the report, select Small Group Display under Report Options to allow this data to appear on reports.
