I want to perform an association analysis between a binary (dichotomous?) variable and continuous variable. The binary variable is whether something is present or not, "Yes" or "No"/ "1" or "0" .... etc. The continuous variable are numbers between ~150 and 170~. The continuous variable is not normally distributed. There are more low than high values. My question of interest is whether there is a correlation between either high or low values of the continuous variable and the 1 or 0 of the binary variable. So, do low values correlate with "1"? My sample size is ~150

I have tried a point biserial correlation test and a sperman's rho test so far. I'm not sure if any of them is the right one. Can someone give me an advice on this?

Many Thanks!
