Question

find the mean, \\( \overline { x } \\), of the data.
156, 90, 146, 132, 122, 134
\\( \overline { x } = \\)

Explanation:

Step1: Calculate the sum of the data

$$156 + 90+146+132+122+134=(156 + 146)+(90+132)+(122+134)=302 + 222+256 = 780$$

Step2: Calculate the number of data points

There are \(n = 6\) data points.

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), so \(\bar{x}=\frac{780}{6}=130\)

Answer:

\(130\)
