Wondering if anyone can clarify. I have some results from lit of a sample mean estimate, and 95% CI's. I can use the CI's to calculate the standard error of the mean. If we I want to find the standard deviation and don't know the population estimates do I interpret the standard error of the sample mean as the standard deviation?
I only have this info to work with: mean=-0.32, 95% CI -0.60 to -0.05, n=3090).
