In graph theory, classes refer to categories or groups of vertices (nodes) or edges that share common properties or characteristics. For example, in a bipartite graph, the vertex set can be divided into two distinct classes such that edges only connect vertices from different classes. Classes can also be used to describe partitions of a graph based on certain attributes, such as connectivity or color. Understanding these classes helps in analyzing the structure and behavior of the graph.
Pie chart or circle graph!
An ogive is a type of graph that is used to represent the cumulative frequencies for the classes in a frequency distribution. This type of graph can also be known as a cumulative frequency graph. The cumulative frequency is the sum of the frequencies accumulated up to the upper boundary of a class in the distribution.
A discrete graph is a type of graph that represents data points as distinct, separate values rather than continuous lines. In a discrete graph, the points are plotted individually, often connected by lines or left unconnected, to illustrate relationships between the variables. This type of graph is commonly used in situations where the data involves distinct categories or counts, such as the number of students in different classes or the results of a survey.
bar graph, double bar graph, line graph, and picto graph
A graph with finite data is one that represents a limited number of discrete points or values. For example, a bar graph illustrating the number of students in different classes at a school is finite, as it only includes specific, countable data points. Similarly, a scatter plot showing the relationship between two variables collected from a survey of a fixed number of respondents is also finite. In contrast, a continuous graph, like a sine wave, represents an infinite set of data points.
No it is not. The ogive is a graph that represents the cumulative frequencies for the classes in a frequency distribution.
to draw a graph
Yes. A bar graph of frequencies for classes of heights seems a perfectly sensible way to present the information.
It depends on what the graph is about. For example, if you were making a graph about how many students in each class, you would put the classes on the bottom, or x axis, and the amounts of students on the side, or y axis.

A bar graph cannot have classes with different width. The height of a bar graph represents the frequency attributed to that class whereas in a histogram the area of a "bar" is proportional to the frequency, the height represents the frequency density.

Ogives are often used in statistics to represent the cumulative frequencies for the classes in a frequency distribution.
To make the graph symmetrical
Histograms are generally used when quantitative information is presented for groups (classes) of different sizes (class widths).
