what is the difference between cumulative frequency distribution and frequency distribution

Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interva..

Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interval. This is explained by an example below. The following frequency distribution table gives t..

A teacher gave a test to a class of 26 students. The maximum mark is 5. The marks obtained by the pupils are: Such data as above is called ungrouped (or raw) data. We may arrange the marks in ascending or descending order. The data so represented is called an array. The difference between..

A plot of the cumulative frequency against the upper class boundary with the points joined by line segments. Any continuous cumulative frequency curve, including a cumulative frequency polygon, is called an ogive. There are two ways ..

Identify the incorrect statement. I. The histogram is a graph that displays the data by using continuous vertical bars of various heights to represent the frequencies of classes. II. The frequency polygon is a graph that displays the data by using lines that connect points plott..

In a frequency distribution, the mid-value of each class is obtained. Then on the graph paper, the frequency is plotted against the corresponding mid-value. These points are joined by straight lines. These straight lines may be extended in both directions to meet..

In a frequency distribution, the mid-value of each class is obtained. Then on the graph paper, the frequency is plotted against the corresponding mid-value. These points are joined by straight lines. These straight lines may be extended in both directions to meet the X..

The number of waves, which pass through a given point in one second is known as frequency. It is denoted by the Greek letter n (nu). The unit of frequency is cycle per second or simply reciprocal second (s - 1 ). A cycle is said to be completed when a wave consisting of one ..

In a Botany experiment the lengths (in mm) of 30 leaves measured are as indicated. Choose a table which shows the frequency distribution of the data. => Table - 1 or Table - 2..

With regards to distribution they are of 3 types. National, multi national and internationa..
