Hi All,
I have the following dataset (triplicates values of 5 independent
measurements and duplicate vaues of a control):
1 2 3 4 5 C
181.8 58.2 288.9 273.2 290.9 53.9
120.3 116.8 108.9 281.3 446 39.6
86.1 148.5 52.9 126 150.3
My aim was to find if mean values of Samples 1 - 5 are significantly higher
than the mean value for C (control).
At first, I carried out mean, SD and t-test (one-tail). Although SD error
bars are large, two of the samples have mean values that are significantly
higher than that of C.
Second, I carried out median and Coxon-Mann-Whittney test because of my
worry about the size of my data and the high variations in the replicates. I
was surprised however, that median and Coxon-Mann-Whittney tests did not
reveal statistical significant results.
I will be happy if anyone could adivce me on the best way to analyse this
dataset.
Regards,
Rob
