Question

15 students were asked how many hours per week they listen to music. 3 different graphs were used to record the same data.

Using the 4 displays above. Select which of the following statements are true:
A) The line plot and stem & leaf plot show both individual data and the range of data while the histogram and frequency table do not show both.
B) One of the displays does not show the same information as the others.
C) The first three displays show that as time increases, frequency decreases.
D) The line plot is not labeled properly.
E) The frequency table and the histogram do not use the same ranges.

Answer 1

If you observe the 4 graphical representations you will see that except stem and leaf plot, the rest 3 represent the same information.

As the time is increasing, the frequency of students who listen to music is decreasing. The frequency is maximum for the first group 0 - 1 and least for the last group 6 - 7.

The ranges shown in both Frequency Table and Histogram are the same.

So, the following options are correct:
B) One of the displays does not show the same information as the others.
C) The first three displays show that as time increases, frequency decreases.
