Usage
What’s the difference between mode, median, mean, and average? In the context of mathematics and statistics, the mode of a set of values is the most frequently repeated value in the set. In contrast, the median is the middle number in a set of values when those values are arranged from smallest to largest. The word mean refers to what’s informally called the average—the sum of a set of values divided by the number of values. The word average is of course also very commonly used in more general ways. In math, though, it’s helpful to use more specific terms when determining the most representative or common value in a set of numbers. To illustrate the difference, let’s look at an example set of seven values: 2, 3, 3, 4, 6, 8, 9. The mode is simply the value that shows up the most. In the example set, the mode is 3, since it occurs twice and all the other values occur only once. To get the mean of this set, you’d add up all the values (2+3+3+4+6+8+9=35) and then divide that total by the number of values (7), resulting in a mean of 5. This is what most people are referring to when they refer to the average of some set of numbers. To find the median, you have to find the one that’s sequentially in the middle. In a set of seven numbers arranged in increasing value, the median is the fourth number (since there are three before and three after). In this set (2, 3, 3, 4, 6, 8, 9), the median is 4. When a set has an even number of values, the median is the mean of the two middle values. Want to learn more? Read the full breakdown of the difference between mode, median, mean, and average.

Etymology
Origin of mode1
First recorded in 1250–1300; Middle English mod(e), from Old French or directly from Latin modus “measured amount, limit, manner, kind, tone”

First recorded in 1635–45; from French, from Latin modus; see origin at mode 1
Explanation
You can describe the specific style of doing something as your mode. If you're in vacation mode, for example, it might mean you say everything in a super-relaxed voice and spend all of your classes daydreaming. From the Latin modus or "manner," it has been popular since the 1400s. Since the 1600s, people have been using it as another word for "fashionable." The French term "a la mode" literally means "in the fashion," or "fashionable," but is more commonly used to describe as specific way of serving dessert (ice cream on the side).
