I am working on a biological dataset which is not following ideal normal/gaussian distribution.. Which statistical test and technique would be best to analyze this dataset ??
There are a variety of non-parametric methods to choose from, depending on the research question. It's difficult to give a general answer.
If it is testing differences between independent groups you are intereted in you can use Mann-Whitney's U-test, or Kolmogorov-Smirnov's test. For dependent data there are other tests.
If you provide more information I will be able to give you more detailed suggestions.
Fredrik C Lundin.. I want to test the difference between the independent groups..
THanks for ur suggestion in advance..!!!
What "difference" do you mean?
- a difference in distribution?
- a stocastic difference in magnitude?
- a more specific difference of the distributions (e.g. difference in concentration, in variation, or in some quantile?)
Jochen Wilhelm.. these are biological datsets and i want to check difference in their concentrations..
That information does not make your question clearer. You can substitute "difference" by "concentration difference" in my previous post and the questions remain the same.
If you want a statistical analysis then you must ask a statistical question.
