Question

1.) given the following data below: 70,43,48,72,53,81,76,54,58,64 51,53,75,62,84,67,72,80,88,65 60,43,53,42,57,61,55,75,82,71 draw a stem and leaf diagram for the data given above

Explanation:

Step1: Identify the stems

The data values range from 42 - 88. We will use the tens - digit as the stem. The possible stems are 4, 5, 6, 7, 8.

Step2: List the leaves for each stem

For stem 4: The data values with 4 as the tens - digit are 42, 43, 43, 48. So the leaves are 2, 3, 3, 8.
For stem 5: The data values are 51, 53, 53, 53, 54, 55, 57, 58. So the leaves are 1, 3, 3, 3, 4, 5, 7, 8.
For stem 6: The data values are 60, 61, 62, 64, 65, 67. So the leaves are 0, 1, 2, 4, 5, 7.
For stem 7: The data values are 70, 71, 72, 72, 75, 75, 76. So the leaves are 0, 1, 2, 2, 5, 5, 6.
For stem 8: The data values are 80, 81, 82, 84, 88. So the leaves are 0, 1, 2, 4, 8.
