<math>X_\mathrm{rms}</math> reflects the variation in the function's distance from the average, and is disproportionately impacted by large deviations from the unrectified average value.<ref>{{cite web|title=Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE)|url=http://www.eumetcal.org/resources/ukmeteocal/verification/www/english/msg/ver_cont_var/uos3/uos3_ko1.htm|archive-url=https://web.archive.org/web/20070714143619/http://www.eumetcal.org/resources/ukmeteocal/verification/www/english/msg/ver_cont_var/uos3/uos3_ko1.htm|dead-url-status=yesdead|archive-date=14 July 2007|publisher=The European Virtual Organisation for Meteorological Training|accessdate=30 May 2012}}</ref>

It will always be at least as large as <math>X_\mathrm{arv}</math>, which only measures the absolute distance from said average. The form factor thus cannot be smaller than 1 (a square wave where all momentary values are equally far above or below the average value; see below), and has no theoretical upper limit for functions with sufficient deviation.
