Question

Find the mean with and without the outlier: 66, 55, 65, 44, 54, 10

Answer 1

To calculate the mean of the set of values with the outlier, we will use the formula below

Concept:

An outlier is an observation that lies an abnormal distance from other values in a random sample of a population.

The mean with the outlier will be

`mean=\frac{total\text{ addition of numbers}}{number\text{ of data}}`

By substituting the value, we will have

`\begin{gathered} mean=(66+55+65+44+54+10)/(6) \\ mean=(294)/(6) \\ mean=49 \end{gathered}`

Hence,

The mean of the data with the outlier is = 49
