Testing the equality of two variances
...es
data:
conjps and ms
F = 0.5419, num df = 8,
denom df = 8,
p-value = 0.4045
alternative hypothesis: true ratio of
variances is not equal to 1
95 percent confidence interval:
0.1222368 2.4024170
sample estimates:
ratio of variances
0.5419076
but If conjps is replaced by conjps1: shifting the first value and the last value position
conjps1<-c(11.36,10.45,10.78,10.73,11.11,11.12,11.59,11.04,9.41)
I do believe we get the same result when testing the equity of variance. but how do I distringuish this two cases by testing?
Kind regards,Tammy
