I am trying to use a partial correlation on my data that should include the high temp, low temp, and total count....and control three other factors. When I run a simple correlation, Analyze-Correlate-Bivariate, I am able to attain correlation values. When I run Analyze-Correlate-Partial, then select the high temp, low temp, and total count as my variables and the rest as my controlling for I do not get any correlation values and it gives me a df of 0. There are five rows for each variable, could it be there is just not enough data to do a partial? Please any help as to why the simple correlation works but the partial correlation does not work would be great.
