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
histogram
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.
First, you need a frequency table.
The frequency in a frequency table is the number of occurrences within each class width. The total frequency is the sum of all frequency's within all the classes.
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.
a specific point mark or degree

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.
