    Median Fold Change and Interquartile Range. 2 non-normal non-paired groups.

    I have a query concerning data presentation using biological data. I would like to present the median fold change between a control and test group. So i have 8 values in each group - i would like to present: a) The median fold change (for this i will take the median of each group and then...

    Non parametric multivariate analysis?

    Hi this is a pretty straightforward question, what analysis allows multivariate analysis that is also non parametric? I would like to analyse the relationship between one response variable(continuous, non normal data) with 2 independent predictor variables(both categorical). So the anova...

    Interaction effects, distributions not normal- is ANOVA justified??

    Hi! I have a 2*4*6 factorial design. the sample distributions in most cases are NOT normal (tested with Kolmogorov-Smirnof test). It is recommended to use non-parametric tests in such cases but my question is this: What test should I use to test for interaction effects? Thank you!
