      The formula was developed by the statistician Franklin E. Satterthwaite and a derivation of the result is given in Satterthwaite's article in Psychometrika (vol. 6, no. 5, October 1941). My aim here is to translate Satterthwaite's work into terms that are easily understood by AP Statistics teachers.
