### Finding the Mode

The mode refers to the number in a set of numbers that occurs most frequently. To find the mode, you just look for numbers that occur more than once and find the one that appears most often.

Examples
1. Find the mode of the following set of numbers: 5, 7, 9, 12, 9, 11, 15.
2. The number 9 occurs twice in the list, so 9 is the mode.

3. Find the mode of the following set of numbers: 5, 7, 19, 12, 4, 11, 15.
4. None of the numbers occurs more than once, so there is no mode.

5. Find the mode of the following set of numbers: 5, 7, 9, 12, 9, 11, 5.
6. The numbers 5 and 9 both occur twice in the list, so both 5 and 9 are modes. When a set of numbers had two modes, it is called bimodal.

As you can see, the mode isn't always a middle number in a set of numbers. Instead, mode shows clustering. Mode is often used in stores to decide which sizes, styles, or prices are most popular. It wouldn't make sense for a clothing store to stock up on the mean size or the median size of pants. It makes more sense to buy the sizes that most people wear. There's where the mode comes in.
