Re: Mixed 2-way ANOVA

Just to clarify, the study is looking at 3 different 'reach' measures,
when there is a ladder in place (the size of the ladder is dependant on
the several factors, including the height of the participant, and comes
in 3 sizes); and when there is not a ladder in place (the control).
Therefore for each of the 3 'reach' measures i was going to pair:

no ladder - ladder : paired t-test for difs in reach measure 1
no ladder - ladder : paired t-test for difs in reach measure 2
no ladder - ladder : paired t-test for difs in reach measure 3

and test for differences. From a previous study i have found the mean
population difference, the sd and the power, therefore i can calculate
the sample size. Unless i have confused myself!!
