Describe how to construct a stem-and-leaf plot from a set of
data. Assume that the data consist of two-digit numerical
values.
Choose the correct answer below.
A.
First, organize the data into several classes, such as 40-49,
50-59, and so on. Then, tally the number of data items in each
class, and determine the percentage of the population occupied by
each class. Draw a circle, and divide the circle into portions
representing the percentage for each class.
B.
The plot...
