Question

what is the mean? 7 10 10 8 5 1 1

Explanation:

Step1: Calculate the sum of the data

$$7 + 10+10 + 8+5 + 1+1=42$$

Step2: Count the number of data points

There are \(n = 7\) data points.

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). Substitute \(\sum_{i=1}^{n}x_{i}=42\) and \(n = 7\) into the formula: \(\bar{x}=\frac{42}{7}\)

Answer:

\(6\)
