Question

find the mean, \\( \overline { x } \\), of the data.

97, 122, 143, 155, 138

\\( \overline { x } = \\) ?

Explanation:

Step1: Calculate the sum of the data

$$97 + 122+143 + 155+138=655$$

Step2: Divide the sum by the number of data points

There are \(n = 5\) data points. So, \(\bar{x}=\frac{655}{5}\)
$$\frac{655}{5}=131$$

Answer:

\(131\)
