Construct a frequency distribution for 100 employees using intervals of 0-4, 4-8, 8-12, 12-16, 16-20.
To construct a frequency distribution for 100 employees using the given intervals, you'll need to follow these steps:
1. Start by listing the intervals you are going to use:
- Interval 1: 0-4
- Interval 2: 4-8
- Interval 3: 8-12
- Interval 4: 12-16
- Interval 5: 16-20
2. Count the number of employees falling within each interval. For example, if you have 100 employees and you know that 20 of them fall within the 0-4 interval, you'll assign a frequency of 20 to that interval.
3. Record the frequencies for each interval in a table format. Here's an example:
Interval | Frequency
------------|----------
0-4 | 20
4-8 | X
8-12 | Y
12-16 | Z
16-20 | W
4. Continue counting the number of employees in each interval and record the frequencies accordingly.
Note: The values X, Y, Z, and W represent the frequencies that you need to calculate based on the number of employees falling within each respective interval.
Once you have counted the frequencies for all intervals, you will have constructed a frequency distribution for the given data.
