I have to calculate the 95% CI for the IQR. I have 100samples with
continuous numbers using a compute-intensive method.
1)I can calculate the 95%CI and the IQR, but I don't know how to calculate
the CI of the IQR, does anybody have any idea, which method will be
2)I have a 2x2 table with gender vs blue eyes or not. How do I calculate the
expected two-by-two contingency tables? Do I assume that half the people are
female and half are males. And assume some random chance of your eyecolor
3) I have to use a permutation test, to calculate whether there is a
difference in the median of two samples. - How do I do that? I thought
permutation test only was for categorical data?
