As someone with a degree in economics and data science, 40 is TOO small a sample size for the data you are trying to measure considering how large of potential sample pool there actually is (ie- millions of SWers)
it's 40 per bin, total of around 160. which is still small, but you probably know there's statistical tools to tell you exactly how much you can predict given the data you have; e.g., the confidence intervals
I will keep saying the same problem with your data- your sample size is not representative of the SWing industry becaUe of how the data was gathered and how much of the population in the industry it excludes. Its representative of SWers that scrolled through social media.
