Question

find the mode and the range for the data.
(a) mode:
(b) range:
ten students were asked how many books they read last summer. their answers are shown in the dot plot (is sometimes called a \line plot\.)

Explanation:

Step1: Find the mode

The mode is the value that appears most frequently. In the line - plot, the number of dots (which represents the frequency of each value) is highest for the value \(7\). So the mode is \(7\).

Step2: Find the range

The range is calculated as \( \text{Range}=\text{Maximum value}-\text{Minimum value}\). The maximum value in the data (from the line - plot) is \(8\) and the minimum value is \(2\). So, \(\text{Range}=8 - 2=6\)

Answer:

(a) Mode: \(7\)
(b) Range: \(6\)
