Which data display allows us to split the data into more groups?
Histogram, see solution.
15,21, 18, 10, 12, 11, 17, 18, 16, 12,20, 12, 17, 16 We are asked which display best represents the given data: a histogram or a stem-and-leaf plot. Since most of the data are between 10 and 19, in a stem-and-leaf plot the data will be concentrated in the stem 10. This will not show the distribution properly. Conversely, a histogram can be divided into more intervals to show the distribution better. Therefore, a histogram would best represent the data.
