**160**wrote:A very naive question I want to show significance differences in distribution of two tests of values, I an easily show by box plot and have confidence of interval calculated. I have see several papers also showing a p value. How can I calculate p value to show differences among two box plots. A google search showed that CI an p values are calculated from same formula. Then how can I get p value either from CI or from a different calculation from two distributions

Thanks

The box plot is only a way of displaying data.

Statistical tests are based on the underlying dataset. What kind of data do you have?

1.2kI have gee expression between disease vs control

160Across multiple genes? The more information you give, the more people can help.

Is it something like this?

Fpkm Comparison Using T-Test Or Mann-Whitney U Test

1.2k4 groups with 10 replicates : two normal groups untreated/ treated; two groups of disease untreated/ treated . DE was calculated using ANOVA.
