Use your data to make a frequency table by age, with 7 classes, starting at age 10 with a class width of 10.
We have no access to the ages in your class.
To create a frequency table by age with 7 classes, starting at age 10 and with a class width of 10, you need a dataset that includes the ages of individuals. Once you have the dataset, follow these steps:
1. Sort the ages in ascending order.
2. Determine the minimum and maximum ages in the dataset.
3. Calculate the range by subtracting the minimum age from the maximum age.
4. Calculate the class width by dividing the range by the desired number of classes (7 in this case). Round up to the nearest whole number to avoid fractional class widths.
5. Determine the class boundaries by starting at the minimum age and adding the class width repeatedly until you reach the maximum age. Record the class boundaries for each class.
- For example, if the minimum age is 10 and the class width is 10, the class boundaries would be: 10-19, 20-29, 30-39, 40-49, 50-59, 60-69, and 70-79.
6. Create a frequency distribution table with the determined class boundaries.
7. Count the number of individuals falling within each class and record the frequencies in the table.
Here's an example of what your frequency table might look like:
Age Range | Frequency
-------------------------
10-19 | 20
20-29 | 34
30-39 | 15
40-49 | 10
50-59 | 25
60-69 | 17
70-79 | 5
Remember, this example is based on fictional data. You will need to replace it with your own dataset to get accurate results.
