Hi everyone! I am not very good with stats an I am trying to identify the significance of any variation from a baseline value for the control groups in my meta-analysis. I have the following data for each study included in my meta-analysis:
-sample size of control group
-mean of each control group
-standard deviation of each control group
I want to compare the overall deviation from a baseline value of 220.
What would be the best test to conduct on this data and what would be the best way to visualize it?
Thank you for your help!
