use the following information to calculate a one-sample t-test, and then determine both the cohen's d and r?
effect sizes:
= 45, sample n=9, m = 49, s = 12 (note that you can multiply "s" by itself to get s? ) [g& w chp. 9, one-sample
t-test]
t-1.000; cohen's d -0.333,2 -0.111
t-1.000: cohen's d=0.200.2 - 0.100
t-1.682: cohen's d = 0.333.2 -0.111
t-1.682: cohen's d -0.385,2 -0.111
