generally in this type of loose research with tons of variables that impact stuff, <0.2 is a small correlation, and stuff 0.4-0.5 and higher is really big. A correlation of 1 means it's basically the same thing - it would mean height and weight are so correlated theyre the same #

if I ask 10 people their height and weight, and it's not correlated at all (we can run a test to check the correlation number), we have a few questions - did we just randomly draw a 'bad' 10 people to check? If we gather more people, will we see a correlation?
