Consider the following data for a single group repeated-measures design: k = 4, n = 8, E = .70, a = .Ot (a) Find the critical values for the unadjusted test, for the Greenhouse-Geisser test and for the conservative test. (b) Suppose an investigator had obtained F = 3.29 for the above case and had applied the unadjusted test. What type of error would he make? (c) Suppose a different investigator had obtained F = 4.03 and applied the conservative test. What type of error would he make?
