Hi, I trying to recreate the minitab formula(so that I can use it in Matlab) for calculating standard error of mean as shown in this link Step 2 ( http://support.minitab.com/en-us/minitab-express/1/help-and-how-to/modeling-statistics/anova/how-to/two-way-anova/interpret-the-results/key-results/ ). However, I am unable to get the answer as shown on the web ? is there anyone who knows how ?

The Minitab site doesn’t show the calculation, so I assume it’s the usual definition:
data = rand(1, 10);
SEM = std(data)/sqrt(length(data)); % Standard Error Of The Mean
