I am confused that whether the variance used in the formula from Borenstein's method is the square of standard deviation or standard error of the mean? Could you help me? I thought it should be SD. However, at page 230 from the book (introduction to Meta-analysis) mentioned that "variance is 0.0036 and standard error is 0.06".
