Question

Brady surveyed 20 students and recorded the following data:

50 56 61 51 51 56 82 54 78 68 53 78 69 80 51 76 50 69 80 63
Construct stem-and-leaf diagram: 4| 5| 6| 7| 8|

Answer 1

To construct a stem-and-leaf diagram, separate each number into stem and leaf, then list the stems and corresponding leaves.

Step-by-step explanation:

To construct a stem-and-leaf diagram for the given data, we start by separating each number into a stem and a leaf. The stem will be the tens digit of each number, and the leaf will be the units digit. Then, we list the stems in ascending order and write the corresponding leaves next to them.

The given data is:

50 56 61 51 51 56 82 54 78 68 53 78 69 80 51 76 50 69 80 63

The stem-and-leaf diagram is:

4 | 50 50 51 51 53 54 56 56 61 63

5 |

6 | 68 69 69

7 | 76 78 78

8 | 82 80 80
