Question

find the mean of:
15 38 34 22 2 23 21 23
27 26 14 32 30 1
mean =

Explanation:

Step1: Count the number of values

There are 14 numbers: 15, 38, 34, 22, 2, 23, 21, 23, 27, 26, 14, 32, 30, 1.

Step2: Calculate the sum of the values

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), where \(n = 14\) and \(\sum_{i=1}^{n}x_{i}=308\). So \(\bar{x}=\frac{308}{14} = 22\).

Answer:

22
