actually do not think there is a need. I do not have trouble remembering the formula.
Breaking it down into 3 parts
1
1/n
(Xi-XBar)^2/(n-1)*Sx^2
helps me keep it in mind.
if you referred to searched for Level II posts by mvwt9 -> he had used the Confidence interval method - and selected the one slightly higher... or something like that, instead of memorizing this formula.
