Question

find the mean of the following set of numbers.
8,5,9,5,5,7,3
mean =

Explanation:

Step1: Calculate the sum of the numbers

$$8 + 5+9 + 5+5+7+3=42$$

Step2: Count the number of elements

There are \(n = 7\) numbers.

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: \(\bar{x}=\frac{42}{7}=6\)

Answer:

\(6\)
