Hi Bill,
Yes, sort of. We used the collector in the sampler plugin and got a random sample of 10. We wanted to pull those 10 out of the total population and compare the mean of the sample with the mean of the total population without the 10. We can do it manually finding each observation from the sample and setting it aside in the main dataset, but that can be quite tedious. So we were wondering if there was a way to highlight all of the observations the sampler pulled in the larger dataset.
