Mean Calculation
1. Let's start by defining the problem: finding the mean (average) of a set of values given in a table.
2. The mean is calculated by summing all the values and then dividing by the total number of values.
3. Suppose the table contains values $x_1, x_2, x_3, \ldots, x_n$.
4. The formula for the mean $\bar{x}$ is:
$$\bar{x} = \frac{x_1 + x_2 + x_3 + \cdots + x_n}{n}$$
5. To compute the mean:
- Add all values from the table to get the sum $S = x_1 + x_2 + \cdots + x_n$.
- Count the number of values $n$.
- Divide the sum $S$ by $n$.
6. This value $\bar{x}$ represents the average of the data in the table.
7. If you provide the actual values, I can demonstrate finding the mean step-by-step with those numbers.
