I hope you are well? I would like some help with the below please:

"Provided we have the mean, standard deviation, and sample size for eachgroup, we then find the difference between means and its standard error in the usualway"

I do have date for the SD, mean and sample size for each group, but how do I calculate the difference between means and the SE from it?

Thank you in advance for your kind help,

Julia
