Question

Here is a data set summarized as a stem-and-leaf plot:

5# | 0022234569

6# | 01145555667779

7# | 01256

8# | 149

How many data values are in this data set? n=

What is the minimum value in the last class? ans =

What is the frequency of the modal class? (Hint, what is the mode?) frequency =

How many of the original values are greater than 70? ans=

Answer #1

Stem and leaf plot can be expressed as below

Class interval. Frequency

50-60 10

60-70 14

70-80 5

80-90 3

Total no of data values in data set, n=32

Minimum value in the last class i.e. in 80-90 is 81.

Mode is the value which appears the most

From the mentioned plot we observe that 65 occurs most times i.e 4 ..

Hence 65 is the mode

And if the modal class is considered 60-70 is Modal class which has maximum frequency =14

No of values greater than 70 are 8 which lie in the last two classes...

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...
