Given:
Numbers of participants in twelve community service days sponsored by a school.
Calculation:
First of all, we will arrange our given data in ascending order as:
Now we will draw two columns. We know that left column of stem and leaf plot represents tens place and right column represents ones place.
Upon using our given data, we will get our required stem and leaf plot as shown below:
To make a histogram, we will make intervals for the number of participants as:
Number of participants | Data points | Number of community service days |
0-10 | 0 | 0 |
11-20 | 12 | 1 |
21-30 | 21, 22, 23, 25 | 4 |
31-40 | 31, 34, 35, 36, 40 | 5 |
41-50 | 42, 42 | 2 |
Upon using our given data, we will get our required stem and leaf plot as shown below:
