Ordering the temperatures in the problem we get: 21 22 25 26 28 28 32. In the example above we have an odd number of data points, so we can just choose the middle numbers after re-ordering them. If you have an even number of data points, then average the middle two numbers in the list. To find the median of a set of data, order the numbers from smallest to largest and choose the data point in the middle. To find the arithmetic mean (also called the average) of a set of data, add up each data point and divide by the total number of data points, in this case 7. In order to solve this problem, we have to perform three calculations to find the mean, median and mode of the nighttime temperatures (the data set), then choose the correct ranking of the mean, median and mode from the multiple choices that are provided.

This tutorial shows how to solve this problem and then how to use your TI-83 Plus, TI-84 Plus, or TI-89 to simplify the process. If m represents the median temperature, f represents the temperature that occurs most often, and a represents the average (arithmetic mean) of the seven temperatures, which of the following is the correct order of m, f, and a?
