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

How do you complete a cumulative frequency table?
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.
How do i calculate cumulative frequencies?
To calculate cumulative frequencies, start by organizing your data in a frequency distribution table. For each class interval, add the frequency of that interval to the cumulative frequency of the previous interval. Begin with the first interval, where the cumulative frequency is simply its frequency, and continue adding each subsequent frequency to the cumulative total. This process will give you a running total of frequencies up to each class interval.
How do you find class mark frequency?
To find the class mark frequency, first determine the midpoint of each class interval by averaging the lower and upper boundaries. Then, tally the number of data points that fall within each class interval to establish the frequency. The class mark is typically used to represent the data points for that interval in further calculations, such as finding the mean. Finally, you can summarize the results in a frequency table for clarity.
How do you find out the cumlative frequancy?
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.
What type of graph displays data from a frequency table and has one bar for each interval of the table that contains values?
histogram
What is a frequency table interval?
equal groups on the table which is the scale
What is the length of an interval in a grouped frequency table?
The length can be found by taking the larger number in the frequency group and subtracting it to find the range.
What is an interval on a frequency table?
a specific point mark or degree

How do you find the frequency in frequency table if the given is percent of total?
find the frequency before finding the percent total -_- :)
What information is available about the data in a regular frequency distribution table that is not available in a grouped table?
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.

Where can one purchase a frequency table?
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.
