Question

Select the mean, median, mode and range of the following list of values.1, 2, 4,7Averages3.5None36MeanMedianRangeMode

Answer 1

The data set is

1, 2, 4, 7

The answers are;

`\begin{gathered} \text{Mean}=(1+2+4+7)/(4) \\ \text{Mean}=(14)/(4) \\ \text{Mean}=3.5 \end{gathered}`
`\begin{gathered} \text{Median}=(2+4)/(2) \\ \text{Median}=(6)/(2) \\ \text{Median}=3 \end{gathered}`

The median in a case where the data set is an even number, then the median would take account of both middle values and then calculate addition of both and then divide by 2

The Mode is the most frequently occuring value in the data set. In this case, all observed data occur just once, and none of them occur more than once. Hence there is no Mode

`\begin{gathered} \text{Range}=\text{Highest value-Lowest value} \\ Range=7-1 \\ \text{Range}=6 \end{gathered}`
