CONCEPT OF BAR CHARTS FOR THE KIDS

Cuemath is that platform which is providing after-school online Math programs to the students of KG to 12th-grade. Their main goal is to overcome the fear of math in the students and to create problem-solvers for the future. They have designed their curriculum in such a way that a child can easily understand the basics of math and can improve his or her reasoning skills while covering the school course. With the help of this article, you can easily grasp the concept of a bar chart.

What is the definition of a bar graph?

A bar graph is one of the statistical tools of data handling. It represents the complete data (usually grouped data) with the help of horizontal or vertical rectangular bars where the bar’s length is proportional to the numerical data they represent. Bar graphs representing grouped data are known as bar charts. A bar graph is plotted across two axes. One axis is used to represent the categories or quantities which are being compared and the other axis represents the values of the variables, like numerical data, percentages, etc which are represented through rectangular bars having equal length and width.

There are five important characteristics of a bar graph:

  1. The bar graph is an ideal tool to compare two or more sets of data.
  2. The width of each rectangular bar is equal and there is equal space between them.
  3. It uses two axes- the X-axis and Y-axis to represents the relationship. One axis represents categories and another one represents discrete values.
  4. The bar graph is used to show the changes in the values concerning time.
  5. All rectangular bars are on a common base and their height is equal to the numerical value they represent.

What are the different types of Bar Charts?

The bars on the bar graph are plotted horizontally or vertically. So, there are mainly two types of bar graphs:

  1. Horizontal Bar Graph: A horizontal bar graph is the pictorial representation of grouped data with the help of proportional horizontal bars. The length of the bars here shows the measure of values. Data is represented on the graph’s x-axis with the help of horizontal bars.
  2. Vertical Bar Graph: a vertical bar graph is the representation of grouped data with the help of proportional vertical bars. The height of the bars here shows the measure of values. It is the y-axis on which numerical data is represented.

The bar graph is classified into two subparts:

  1. Grouped Bar Graph: The grouped bar graph is the pictorial representation of discrete values of multiple categorized data. It is also known as clustered bar graph because it represents two or more groups on a common base. The rectangular bars can be constructed horizontally or vertically. Single color is used to specify one series across the entire set.
  2. Stacked Bar Graph: The stacked bar graph is the pictorial representation of aggregate data divided into different parts. It is also known as a composite bar graph because it divides the whole bar into distinct parts. In the stacked bar graph, different colors are used to specify the categories represented by different parts of the bar.

What are the benefits of a bar graph?

Benefits of Bar Graph:

  1. Bar graph allows easy comparison by presenting the clear relationship between size and numerical quantities.
  2. It is pretty easy to interpret the result.
  3. The bar graph is less complicated and clarifies the trend of data much better as compared to the tables.
  4. It represents the accuracy and reasonableness of calculation visually.
  5. The bar graph represents each category in the frequency distribution.

Bar graphs are easy to understand andcan be used when the given data is to be compared with the help of a chart.As we have discussed the basic concept of bar graphs if you have any doubt related to the concept of line graph you can take the help of Cuemath and can clear all your doubts.
