It looks roughly symmetric. So we can feel okay about this normal distribution. This isn't the best study that one could conduct. This is obviously a small sample size. It's not random of the entire population. But maybe we could go with it. Also, when you think about biological processes, like how well someone snaps, which is a product of a lot of things happening in a human body, and it's the sum of many, many processes, those things also tend to have a roughly normal distribution but I won't go into too much depth there.
