| | Two of the most common characteristics we want to describe about a set of data are its **"central** **tendency"** and its "spread." There are three common measures of **central** **tendency;** the mean, median and mode. |

| | You are correct in eliminating the range as an option - range (along with variance and standard deviation) is a measure of "spread," or distribution of the data, not **central** **tendency**. |
