I'm using SRCC in a piece of Economics coursework to find the relationship between two types of variables.

I'm just wondering if it would be possible to use three variables instead? For example, if I have a set of figures on house prices, population and income, would it be possible for me to rank the three seperately then use the formula?

Thanks for the help!

Sure, actually you can look at a Econometric book, which has many empiracle fromulas.

2 variables just for simplicity and nothing else.
