Question

Find the mean median mode and range for the following list of values: 13,18,13,14,13,16,14,21,13

Answer 1

Given data:

The given obserrvations.

The mean of the given observation is,

`\begin{gathered} m=(13+18+13+14+13+16+14+21+13)/(9) \\ =15 \end{gathered}`

The given data can be arranged as,

13, 13, 13, 13, 14, 14, 16, 18, 21

The medain of the given data is 14.

The mode of the given data is 13.

The range of the given data is,

`\begin{gathered} R=21-13 \\ =8 \end{gathered}`

Thus, the mean of the given data is 15, the median of the given data is 14, the mode of the given data is 13, and range of the given data is 8.
