Question

Answer the statistical measures and create a box and whiskers plot for the followingset of data.I need to also create a box plot

Answer 1

Given the data points:

6, 9, 9, 10, 10, 10, 11, 11, 12, 17, 19, 19

Solution

Min: Minimum number in the set of data:

`Min\text{ = 6}`

Max: Maximum number in the set of data:

`\text{Max = 19}`

Q1: First quartile of the set of data:

First, we obtain the position of the point using the formula:

`Q_1\text{ = }(n+1)/(4)`

Hence,

`\begin{gathered} Q_1\text{ = }(12+1)/(4) \\ Q_1\text{ = 3.25th} \end{gathered}`

Q1 is between 9 and 10. Thus:

`Q_1\text{ = 9.25}`
