I could only find one result from Yahoo Answers, but the answer wasn't clear on the exact meaning of variability and how it is different from variance.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.

Variance is a measure of variability found.

The temperature of a given place will be variable. If we measure the temperature over a given period, we will have a set of results. We can then calculate the variance of those results, giving us a measure of that variability.
