Hi,
I would like to compare two groups, one treated, one control.
Usually, I would simply use a t-test, assuming normal distribution
and equal variance.
However, I would now like to use another parameter as a co-factor:
I am comparing two groups of animals and the effect I observe
could be due to a difference in weight.
Which test can account for this? I know that if I had three groups
or more I could use one-way ANOVA, but since I only have two groups...
Probably, this is a very basic question, I'm just not very firm with stats.
Thanks for your help
