Question

The following table shows the average number of songs downloaded each day by some students of a class:


Student A B C D E F G H I J K L M N O
Songs 3.4 1.1 1.7 3.1 5.8 3.2 3.7 3.4 1.6 3.5 3.9 3.8 1.1 1.9 1.8


Which histogram best represents the data?
Histogram plots number of songs downloaded each week on x axis and number of students on y axis. Height of the bar in the x interval 0 to 2 is 6, height of the bar in the x interval 2 to 4 is 8, and the height of the bar in the x interval 4 to 6 is 1.

Answer 1

the answer choices are hard to understand in text form, but look for the histogram that accurately represents the data (count how many data points fall into each interval, and see if the graph and data match). also, consider readability (the intervals should be evenly spaced, and scaled to make the bar graphs easy to read and compare)
