Draw the histogram of hours for 20 students.
Expert Solution & Answer
Explanation of Solution
Figure-1 illustrates the histogram of hours for 20 students as follows:
Stem-and-leaf display:
The stem-and-leaf display is an exploratory data analysis (EDA) that is an alternative method of histogram in which data are grouped according to their leading digits, it is called ‘stems’, and the final digits, called ‘leafs, are listed separately for each member of a class. Here, the leaves are displayed individually in the ascending order after each of the steams.
Table 1 indicates the stem-and-leaf display using the given data (Data file Sun).
