I'm thinking of tabulating the mean of each of these factors for several successive distance brackets, i.e. 0-10 miles, 10-20 miles etc. So distance isn't really continuous even though this is my dependent variable. Would you use multiple linear regression for this? Could I simply assign a number to each bracket, and interpret it that way, i.e. 0-10 miles = 1, 10-20 miles = 2.

Does it make sense to test whether these factors are predictive of distance? I'm simply trying to see if there are any correlations between distance and these factors, and so far MLR seems to be the way to go.
