Dear community I'm pretty new to R and I'm trying to do a Point-baserial correlation for a nominal dichotomous variable with a interval scaled variable. It works fine, but the output just shows me the correlation and nothing else (p-Value would be important). I tried it with the following codes: - biseral.cor() - cor.biseral() - I also tried a polyserial() I've found on this question page: http://stackoverflow.com/questions/35880910/point-biserial-and-p-value Problem: It's not working (telling me y has fewer than 2 levels) and it would also be for a ordinal dichotomous variable, but I only have a nominal dichotomous variable. In the forum if found following Syntax that I've tried out: https://stat.ethz.ch/pipermail/r-help/2003-April/031852.html It seams to work because I don't get any error messages but I'm not getting an output either. I'm really thankful for every help I could get on this topic or tips where I can find out and learn how to find a correlation with a p-value in R for a nominal dichotomous and an interval scaled variable. Thanks in advance and have a nice weekend! [[alternative HTML version deleted]]
