Question 1 Report
Use the bar chart in the diagram to answer this question about reading. The chart shows how many books each of six students read in one month. Work out the mean number of books. Then state the modal number and the range.
Answer Details
The bar heights give the values \(3,5,4,5,8,5\).
\[3+5+4+5+8+5=30\text{ books}\] [M1]
\[\text{mean}=30\div6=5\text{ books}\]
The mean is \(5\) books [A1]. The value occurring most often is \(5\), so the mode is \(5\) books [B1]. The largest value is \(8\) and the smallest is \(3\), hence \(8-3=5\): the range is \(5\) books [B1].
