Your claim is that the selection of participants didn't affect the answers, instead that the variability is natural and random, caused by the small sample size. Seems to be a very strong statement given things like selection bias. Now if you want something to point fingers at there's tons of confounding factors on this kind of survey on an anonymous "private" social media app anyway
that is not at all what im claiming😭 if the sample size was larger it would likely have more variability & therefore be more representative of the general population (if thats the population op is looking to represent). thats what i mean. i agree there r def other variables at play here & by listing sample size as a potential issue im not attempting to rule out the other issues just listing one i see as problematic that no one else had mentioned
