Hello,
If the lowest class limit is 0-9 then how do I figure out the frequency, Midpoint, Relative frequency, and cumulative frequency?

By dividing the range into 5 equal parts.
The minimum is 0 and the maximum is 49.
So pick 0-9, 10-19, 20-29, 30-39, 40-49.

Frequency is the number of times a particular value or data point occurs in a dataset. It is often represented by the symbol 'f' and is an important measure in statistics and data analysis.
To calculate frequency, you need to count the number of times a specific value occurs in a dataset. For example, if you have a dataset of test scores and want to find the frequency of scores above 80, you would count the number of scores that are greater than 80 in the dataset.
The midpoint, also known as the mean, is the average of a dataset. It is calculated by adding all the values in the dataset and dividing by the total number of values. The midpoint is often used as a measure of central tendency in statistics.
Relative frequency is the proportion of a specific value in a dataset compared to the total number of values in the dataset. It is calculated by dividing the frequency of a particular value by the total number of values in the dataset. This is often expressed as a percentage.
Cumulative frequency is the sum of all frequencies up to a certain value in a dataset. It is often used to show the progression of values in a dataset and is useful for identifying patterns or trends. Cumulative frequency can also be expressed as a percentage of the total number of values in the dataset.
