What is cumolative frequency curve?

A cumulative frequency curve is a graph that shows the cumulative frequency of a data set. This type of graph can present data, such as medians and quartiles. Another name for this curve is an Ogive.

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.

What is utility of cumulative frequency curve?

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.

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.

What is cumulative frequency?

Cumulative frequency is the running total of class frequencies.

What does cumulative frequency graph measure?

If the frequency is 3 what is the cumulative frequency?

It is 3 more than the cumulative frequency up to the previous class or value.

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.

How do you set up a box and whiskers plot with multiple numbers?

By transferring the numerical data from the cumulative frequency curve into a box and whiskers plot.
