Question

find the standard deviation of the given data. first, find the mean, \\(\overline{x}\\), of the data. 5, 6, 8, 13 \\(\overline{x} = ?\\)

Explanation:

Step1: Sum the data values

The data values are 5, 6, 8, 13. Their sum is $5 + 6 + 8 + 13 = 32$.

Step2: Divide by the number of data points

There are 4 data points. So the mean $\overline{x}$ is $\frac{32}{4} = 8$.

Answer:

8
