Final Answer:
The frequency distribution using the given classes would be:
- 12–14: 3
- 15–17: 4
- 18–20: 5
- 21–23: 4
- 24–26: 4
Step-by-step explanation:
To develop a frequency distribution using the given classes, we need to determine the number of data points that fall within each class.
Let's assume we have a dataset of ages and we want to create a frequency distribution using the classes 12–14, 15–17, 18–20, 21–23, and 24–26.
To create the frequency distribution, we count the number of data points that fall within each class. For example, if we have 20 data points with ages ranging from 12 to 26, we would count how many of those data points fall within each class.
We have the following data:
13, 15, 17, 19, 22, 24, 24, 26, 26, 14, 18, 21, 23, 15, 18, 20, 25, 13, 14, 18
To create the frequency distribution, we count how many data points fall within each class:
12–14: 3 data points (13, 14, 13)
15–17: 4 data points (15, 17, 15, 14)
18–20: 5 data points (19, 18, 18, 20, 18)
21–23: 4 data points (22, 21, 23, 25)
24–26: 4 data points (24, 24, 26, 26)
Hence, the frequency distribution are:
12–14: 3
15–17: 4
18–20: 5
21–23: 4
24–26: 4
Each number represents the frequency, or the number of data points, that fall within each class.
