Question

find the mean for the following group of data items. 58, 55, 57, 50, 55, 61 the mean is (type an integer or a decimal.)

Explanation:

Step1: Calculate the sum of data items

$$58 + 55+57 + 50+55 + 61=336$$

Step2: Count the number of data items

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

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), so \(\bar{x}=\frac{336}{6}=56\)

Answer:

\(56\)
