The term "mean" typically refers to the average of a set of numbers. To calculate the mean, you follow these steps:

1. Sum all the values in the set.
2. Divide the total by the number of values in the set.

For example, if you have the numbers 2, 4, 6, 8, and 10:

• Sum of numbers: $2 + 4 + 6 + 8 + 10 = 30$
• Number of values: 5
• Mean: $\frac{30}{5} = 6$

So, the mean (or average) of these numbers is 6.

In more advanced contexts, "mean" can have different meanings, such as in statistics or when applied to weighted averages. But in basic terms, it is the sum of values divided by how many values there are.

Here are five related questions you might find interesting:

1. How do you calculate the median and mode, and how are they different from the mean?
2. What is the difference between a sample mean and a population mean?
3. How does the mean relate to normal distributions in statistics?
4. What are outliers, and how do they affect the mean?
5. How do you calculate a weighted mean?

Tip: The mean can sometimes be misleading if there are extreme values (outliers) in the data set. It's important to consider other measures like the median.
