Math in quick way - to solve bar graph in mathematics

A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart.

A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific categories being compared, and the other axis represents a measured value. Some bar graphs present bars clustered in groups of more than one, showing the values of more than one measured variable.

In this course, you have learned many types of bar graphs

Mainly There are five Types of Bar Diagram

1. Simple Bar Diagram

2. Multiple Bar Diagram

3. Compound Bar Diagram

4. Percent Bar Diagram

5. Horizontal Bar Diagram

I just cover different types of Bar graphs and questions related to that and also cover topic related questions and some extra questions for practice.

What is a Graph?

In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
The points on the graph often represent the relationship between two or more things.

Here, for instance, we can represent the data given below, the type and number of school supplies used by students in a class, on a graph. We begin by counting each supply and representing the data in particular colors in a systematic order in a table.

Bar Graph

A bar graph is the representation of numerical data by rectangles (or bars) of equal width and varying height. The gap between one bar and another is uniform throughout. Bar graphs can be either horizontal or vertical. The height or length of each bar relates directly to its value.

Line Graph:

A line graph uses dots connected by lines to show the changes over a period of time.

Pie Chart:

The pie chart is also known as a circle graph. It shows how a whole is divided into different parts. The pie chart shows the relative size of each data set in proportion to the entire data set. Percentages are used to show how much of the whole each category occupies.
