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.

What is cumalative frequency?
cumulative frequency is a type of thing that you times with the original number to get a new one.

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 work out a cumulative frequency question?
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.)
What is the ratio of a frequency to its total frequency?
The ration of a frequency to its total frequency is called relative frequency.
What is cumalative frequency?
cumulative frequency is a type of thing that you times with the original number to get a new one.

Is it possible to make an Electronic Pest Repellent using Arduino and make ultrasound from 30khz to 200khz frequency?
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.
In telegraphy how you are using frequency shift keying?
Like in modems, you make digital zeros one frequency and digital ones another frequency.

In a stringed instrument the sound frequency of a particular string can be increased by?
Tightening the string will make its' frequency higher.
Can a frequency produced by a guitar make objects in your house resonate?
Yes it can but the pitch of your frequency should be high
How does frequency of a wave compare with the frequency of the source?
The frequency of a wave is the same as the frequency of the source that produces it. The frequency of a wave is determined by the frequency of the vibrating source that creates it, so they are directly related.
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.
