First, you decide how many intervals you need. (Can be between 5-15).
Then, you find the range (Max-Min=Range)
Next you divide the range by the amount of intervals you wanted.
The quotient is the width of your data
Example:
Intervals(Width=10 and Minimum=28)(When you add the width to the minimum, you should count the minimum too. Instead of 28+10=38, it would be 37 since the 28 count, and to check the answer you have to add ten going down)
28-37
38-47
48-57
58-67
68-77
To complete a cumulative frequency table, start by organizing your data in a frequency table, listing the class intervals and their corresponding frequencies. Then, calculate the cumulative frequency for each class interval by adding the frequency of the current interval to the cumulative frequency of the previous interval. Continue this process down the table until all intervals are included, ensuring that the last cumulative frequency equals the total number of observations. Finally, verify that your cumulative frequencies are in non-decreasing order.
Cumulative frequency is found by adding the frequency of each class interval to the sum of the frequencies of all previous intervals. To calculate it, you start with the first interval, where the cumulative frequency is simply the frequency of that interval. For subsequent intervals, you add the frequency of the current interval to the cumulative frequency of the previous interval. This process continues until all intervals are accounted for, resulting in a cumulative frequency distribution.

find the frequency before finding the percent total -_- :)
You find the total of all the frequencies, N. Then the percentage for any frequency is 100*frequency/N.
equal groups on the table which is the scale
The length can be found by taking the larger number in the frequency group and subtracting it to find the range.

The interval identifier for the keyword "frequency" is "f."

A regular fequency table reports the exact frequency for each category on the scale of measurement. However, when the categories are grouped together into class intervals, the table only reports only overall frequency for the interval but will not show how many scores are in each of the individual categories.

A frequency table is not something that one can purchase. This is a mathematical table that is used for statistics. One can find much more detail about frequency tables on the Wikipedia website.
