Hi im 15 n i am doing my maths coursework which requires me to make a few cumulative frequency curves. Basically all you do is add the frequency as you go along. for example if the frequencies were:
4
5
2
3
then the cumulative frequency would be
4
9
11
14
You would then use this by plotting it along the y axis. There is a little more but that's mainly what u need to know to get started.
cumulative frequency is a type of thing that you times with the original number to get a new one.

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.
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.)
The ration of a frequency to its total frequency is called relative frequency.
cumulative frequency is a type of thing that you times with the original number to get a new one.
It is something u do to take a risks
It is not necessarily so.

To make sound frequency change alter the pitch.
Yes it is possible to make an Electronic Pest Repellent using Arduino and possible to make ultrasound for 30khz to 200khz frequency; you must make a rectangle signal with a frequency and amplify it with transistors.
Like in modems, you make digital zeros one frequency and digital ones another frequency.
The frequency of earthquakes in that region has increased dramatically in recent years.
i just asked for a frequency detector jst as brain wave detector.
The frequency of a radio wave compares to the frequency of the vibrating electrons that make it because the frequency of a radio wave is proportional to the frequency of the vibrating electrons that make it.
Tightening the string will make its' frequency higher.
The frequency of a pendulum is 1 divided by (the number of seconds to make one complete swing)
