continuous classes in frequency distribution

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 ..

Frequency Distribution - 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 represent..

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 tab..

We have so far dealt with discrete charges but a system of charges can be considered as a continuous distribution if the group of charges are located very close together. To find the electric field due to a continuous charge distribution we have to define the..

Moment of Inertia of Continuous Mass Distribution - If a body is assumed to be continuous, one can use the technique of integration to obtain its moment of inertia about a given li..

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 directio..

Geological Distribution - The organisms show particular patterns of distribution on earth. The distribution of the species give an indication of how the earth was earlier. It is believed that the earth was a single mass called the Pangea. It consisted of two large cont..
