# Sample means vs variables in sample

We're using standard error not standard deviation.. why are we assuming that the values in the dataset are nine sample means and not just nine individual values in one sample?

Hello Heather!

Thanks for reaching out!

It's just how we approach the problem from the beginning. We assume that we have 9 different sample means.
