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}
