Question 1 Report

Work out the median of these ten numbers. The diagram shows the same ten numbers plotted in the order given.

\(12,\ 7,\ 15,\ 9,\ 20,\ 4,\ 11,\ 18,\ 6,\ 14\)

You must show the working that you use.

Answer

Answer Details

Order the data before identifying the middle values:

\[4,\ 6,\ 7,\ 9,\ 11,\ 12,\ 14,\ 15,\ 18,\ 20\] [M1]

There are ten values, so use the fifth and sixth values:

\[\text{median}=\frac{11+12}{2}=11.5\]

The median is \(11.5\) [A1].
