Question

On your own sheet of paper, make a stem-and-leaf plot of the following set of data and then find the range of the data.

Answer 1

Answer:

Step-by-step explanation:

The given set of data is 83, 71, 62, 86, 90, 95, 61, 60, 87, 72, 95, 74, 82, 54, 99, 62, 78, 76, 84, 92.

Now the stem - leaf plot will be,

5  4

6  0   1   2   2

7   1   2  4   6    8

8 2   3  4   6    7

9  0   2  5   5   9

Since range of the data = Highest term of the data - Lowest term of the data

                                       = 99 - 54

                                       = 45

Therefore, range of the data set is 45.

Answer 2

The range of the data is 45.

• The calculation is as follows:

As we know that

Since range of the data = Highest term of the data - Lowest term of the data

= 99 - 54

= 45
