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.
The ration of a frequency to its total frequency is called relative frequency.
frequency meter is used to measure the frequency of unknown frequency signal.
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.
Period = 1 / frequency
