To find the mean (also known as the average) of a set of numbers, follow these steps:

1. **Add up all the numbers** in the set to get the total sum.
2. **Count the number of numbers** in the set.
3. **Divide the total sum** by the count of the numbers.

### Formula for the Mean
If you have a set of numbers \(x_1, x_2, x_3, \ldots, x_n\), the mean \(\bar{x}\) is calculated as:

\[
\bar{x} = \frac{x_1 + x_2 + x_3 + \ldots + x_n}{n}
\]

where:
- \(x_1, x_2, x_3, \ldots, x_n\) are the numbers in the set.
- \(n\) is the total number of numbers in the set.

### Example
Suppose you have the numbers: 4, 8, 6, 5, 3. 

1. Add the numbers: \(4 + 8 + 6 + 5 + 3 = 26\).
2. Count the numbers: There are 5 numbers.
3. Divide the sum by the count: \(\frac{26}{5} = 5.2\).

So, the mean is **5.2**.
