What statistical test can I use to assess validity?Watch
I'm trying to find a statistical test that I can use to assess the validity of two different sets of results, both of which I have calculated a mean for, produced by the same method.
Would standard deviation work? Or would I have to use a different method.
Thanks for any help!
So do you mean variability? Standard deviation shows the variability but is not a statistical test.
If you are trying to compare the mean between two groups of data, you need t-test. It shows whether the mean of two groups of data is significantly different.
Validity refers to whether a study measures or examines what it is trying to measure or examine, if the experiment is carefully controlled, and fits the scientific method, then it is valid.
