hi, hopefully a simple one -> let's assume i have data like this: subject A: 1,0,1,1,0,1,1,1 -> mean=6/8=0.75 subject B: 1,1,1 -> mean=3/3=1
weighted arithmetic mean of A+B-> (8*0.75 + 3*1)/11 = 0.82 -> well that was easy, but what if i do have 20 subjects like this and i want to compare their weighted arithmetic mean to the weighted mean of another group of 20 subjects ?? i guess i need to weight every single subject-mean before running any stat-test. and here is my problem: how do i weight the individual subject means ?? thanks for any help, jan . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
