Hopefully this is a reasonably straightforward question that belongs in this forum but I was wondering whether the sample size requirements (i.e. not too small to be <3-6) for non-parametric methods such as the Mann-Whitney and Wilcoxon Signed Rank test refer to per group (such as each...
Hello and thank you for your response. Sorry I didn't quite understand your comment, but do you mean that while we can assume normality of the sampling distribution for the population correlation coefficient, it is not strong enough to feasibly create a confidence interval?
When constructing a CI for population correlation coefficient (p), I am told you cannot use +/- 1.96 as the sampling distribution is non-normal? However, I am also told that each X and Y are assumed to be pairs of independent observations from a bivariate normal distribution?
