Calculate between and within subgroup variability using jmp (similar to Minitab)?

[#1]

Hello,

How would I go about calculating between and within subgroup variability using jmp (similar to Minitab)? Note: Group sample sizes are different. I am looking to compare various brands of products tested across different vectors. For example, for each brand there is a given quantity of samples tested per vector. and I would like to compare across brands for that vector, specifically between/within group variability.

Thank you,

K.

If you go to Variability plot and select the hot button, there's something called variability summary report that looks like this.
