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.
Cumulative or cummulative?
Cumulative is the correct spelling.It is an adjective, and means: "increasing or increased in quantity, degree, or force by successive additions: the cumulative effect of two years of drought."
What is the difference between discrete and cumulative distributions?
A discrete distribution is one in which the random variable can take only a limited number of values. A cumulative distribution, which can be discrete of continuous, is the sum (if discrete) or integral (if continuous) of the probabilities of all events for which the random variable is less than or equal to the given value.
What is another name for cumulative frequency?
I've occasionally seen "cumulative frequency" shortened to the word "cume".
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.
