Interpret the Goodness of Fit (GOF) p-value to decide if the data is parametric (normal) or nonparametric. t-test: Open Excel, log in both data sets. Go to Add Ins, or Analysis ToolPak, Hypothesis Tests, Compare Two Independent Groups, (Assuming Equal Variances) left mouse click highlight Group 1 then Group 2, OK. Conclude.
