This will purely depend on the question, if you get a frequency chart, (containing only the frequency and how often this was brought, take, etc depending on the question,) add up the frequency one by one and you will have the cumulative frequency. You then (depending on the question) make a chart or a box-plot and follow the question (i.e what if the correlation shown? this would depended on the trend of the data.)

How do you make a cumulative frequency table?

Given a frequency table,the first cumulative frequency is the same as the first frequency;the second cumulative frequency is the sum of the first cumulative frequency and the second [ordinary] frequency;the third cumulative frequency is the sum of the second cumulative frequency and the third [ordinary] frequency;and so on.An alternative definition is that the cumulative frequency for any value is the sum of all the frequencies less than or equal to that value.

How do you find cumulative frequency?

By adding up the (one by one,) the frequency total in order to find the cumulative frequency, most commonly, you just then plot this on a cumulative frequency graph or box plot.

Does cumulative frequency show distribution?

Not directly, but the cumulative frequency contains the same information as the frequencies for the values in question. However, it may not show the full details of the distribution if the values have been grouped.

What is a slope in cumulative frequency?

It is the frequency for that point.

What is cumulative percent?

Cumulative percentage is another way of expressing frequency distribution. It calculates the percentage of the cumulative frequency within each interval, much as relative frequency distribution calculates the percentage of frequency.

What is the difference between a cummulative frequency graph and a cumulative frequency polygon?

A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.

How do you work out a cumulitive frequency?

in a maths question, you have a table. you add up the frequency column, but every time you add something, you write it down, e.g. frequency cumulative frequency 1 1 5 6 3 9 6 15 and so on :)
