by counting the amount of numbers and puting them in a tally.
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.)
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.
you get a range and put all the numbers in their correct range and those together
you can present data in science as many different types of graph: bar chart, pie chart, picto-gram and line graph ( depending on what you are trying to present). also you can present data as a tally chart or even a frequency chart to make the data look more professional and reliable.
