Hi to all,


I would like to generate continuous data for two groups for which I would like to evaluate whether there is a difference between their means (I could use use a t-test). I would like to be able to  set the mean and sd of the two groups. The data would represent bond failure strength (in MPa) of two different materials (the 2 groups). 

Additionally, I would like to generate data for the same experiment that follows the Weibull distribution and compare the two groups.


It is of interest to see the results of the analysis on the data under  the ttest analysis and under an analysis suitable for the Weibull distribution. The objective is to show how different analyses of similar data might point to different results, and the importance of selecting the correct distribution and analysis.

Any advice, references, help would be greatly appreciated.

Best wishes,

Nikolaos
