What is a Histogram?
A graphical representation of the observation or data in vertical or rectangle bars can be defined as a histogram. A rectangle is a geometrical shape where the sides are parallel and opposite to one another. The vertical representation of the observation is defined as the movement from top to bottom or bottom to top. The vertical or rectangle bars are adjacent and represent some sort of data. For instance, the total number of students in a class or the total number of girls in the class is expressed with the help of rectangle bars. There are two axis in a histogram, they are – vertical axis or y-axis and the horizontal axis or the x-axis.
The vertical axis represents the number count or multiple occurrences of the data whereas the horizontal axis, also known as the x-axis expresses the range of outcomes in a data. Various types of histograms signify the different shapes of the histogram. Some of them are bell-shaped histograms, bimodal histograms, uniform histograms, and so on. We shall discuss the types of histogram in a detailed manner.
Types of Histogram Shapes
As mentioned above, a graphical representation of the observation or data in vertical or rectangle bars can be defined as a histogram. The following points analyze the types of histogram shapes:
- A type of histogram shape that has only one peak at the time interval is known as a bell-shaped histogram.
- A type of histogram shape that has two peaks at the time interval is known as a bimodal histogram.
- A type of histogram shape which is skewed to the right is known as the skewed right histogram.
What is a Linear Graph?
The term linear stands for straight. The representation of data in a straight line is known as a linear graph. A straight line is a type of line which is infinite in length if measured. Generally, we use a graph to express or showcase the relationship between two or more than two quantities. A graph represents a relation, when the relation gives a straight line, then the graph is known as the linear graph. We can say that the linear graph is a representation of the linear equation.
Those equations which can be written in the form of AX + BY + C = 0 are known as the linear equation. Here, a, b and c denote the real number. A type of number which is not complex or the variety of numbers including irrational numbers, natural and whole numbers, and many more is defined as a real number. We will discuss how to plot a linear graph
How to Plot an Equation in the Linear Graph?
The representation of data in a straight line is known as a linear graph. We can only plot a linear equation in the linear graphs. The equations which can be written in the form of AX + BY + C = 0 are known as the linear equation. The following steps of plotting a linear equation in a linear graph:
- The first step is to determine the two varying quantities.
- Then, write the first quantity as ‘x’ and the second quantity as ‘y’.
- Now, you may find the order pairs of x and y which will satisfy the given equation.
- Now, write the values in a table or a tabular manner.
- Then, you may plot the points on the graph to represent the linear equation.
Following the steps will help you to plot a linear equation in a linear graph.
