Hi,

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!

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.

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.
In addition, try not to get validity and accuracy confused. As explained above, validity refers to the influence of experimental conduction on results and accuracy is how close the experimental results is to the predicted or actual results(if the experiment was done earlier)
