A Hofstee cut-off calculator. Upload the student scores (percentages), sorted or unsorted, in a single-column .csv file. Enter the parameters (Cmin, Cmax, Fmin and Fmax) either from individual judges (raters) or as a mean or median. Select the data file you wish to use. The app then draws the resultant Hofstee chart, and mathematically calculates the Hofstee cut-off to 2 decimal places. It also indicates, in and around the specified range, the large gaps, so that you can make any small required tweaks. The “Help” screen supplies more information.
