WebThe LSD test was developed by Fisher, Ronald Aylmer (1935), who wanted to know which treatments had a significant effect in an analysis of variance. MATHEMATICAL ASPECTS. If in an analysis of variance the F-ratio leads to rejection of the null hypothesis H 0, we can perform the LSD test in order to detect which means have led H 0 to be rejected.
