A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.
I've occasionally seen "cumulative frequency" shortened to the word "cume".
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
the frequency is less than OR EQUAL TO the cumulative frequency
The cumulative frequency of a random variable X for the value x is the number of observations such that X ? x.
cumulative percentage = (cumulative frequency ÷ n) x 100
You just need to add up the frequency total one by one to find the cumulative frequency of a certain set of 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.
Cumulative frequency is the running total of class frequencies.
a cumulative frequency graph mearsure the cumulative frequency on the y-axis and the class boundaries on the x-axis
The cumulative frequency is the running total of numbers, such as, frequency cumulative frequency 4 4 5 11 6 17 7 24 8 32
It is 3 more than the cumulative frequency up to the previous class or value.

Cumulative percentage is another way of expressing frequency distribution. It calculates the percentage of the cumulative frequency within each interval, much as relative frequency distribution calculates the percentage of frequency.
It is the frequency for that point.
A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.
The main utility of a cumulative frequency curve is to show the distribution of the data points and its skew. It can be used to find the median, the upper and lower quartiles, and the range of the data.
