Bar graphs are a graphical representation of data sets that are used for comparing various items, categories, and observations based on multiple parameters. In order to understand how to solve a simple bar chart, it is crucial to first understand the x and y-axis. The simple bar chart is drawn using a vertical and horizontal bar graph. In the vertical bar graph, the bars are plotted on the graph vertically, whereas, in the horizontal bar graph, the bar is plotted on the graph horizontally. The article gives detailed insight and understanding, along with examples on how to solve a simple bar chart.
What are the different bar graph properties?
These are the different bar graph properties you need to consider while drawing them:
You can draw the rectangular bars vertically as well as horizontally.
All rectangular bars must be placed with equal space and width between them.
The bars should be placed at the same base.
You must remember that the height of the rectangular bars is equal to the data they represent.
These are the important properties you must know to solve a simple bar chart.
Title of Bar Graphs
The title of the bar graphs highlights what the graph represents. It highlights the information which helps in concluding the given graph.
Different Types of Bar Graphs
There are different types of bar graphs that are available in bar graph sample questions. The following section consists of solved examples of bar graphs that help in a better understanding of both the horizontal and vertical bar graphs.
Horizontal Bar Graphs
In horizontal bar graphs, the variables are written horizontally. Thus, the bars are drawn upon the Y-axis, which represents the value of the bars. Hence, the length and its values are equivalent to the variables available in that particular data.
Following is an example of the horizontal bar graph showing the data of age till which people eat chocolates in the form of a graph:
Vertical Bar Graphs
In vertical bar graphs, the rectangular bars are drawn vertically upon the X-axis. Then, the Y-axis represents the height value, highlighting its rectangular bars’ quantity. In the vertical bar graph, the x-axis represents four teams, and the y-axis represents the points earned.
Stacked Bar Graphs
It is also known as a composite bar. In this type of graph, a single bar is divided into several parts. Thus, every part of the bar is coloured differently, highlighting different categories. Furthermore, this type of bar can be drawn both horizontally and vertically.
Grouped Bar Graphs
The grouped bar graph is also important to understand to know how to solve a simple bar chart. It is also called a cluster bar graph. This type of bar graph is drawn to show two or many more categories. Thus, you must analyse the different bars to know how they are drawn. Below is the example of a grouped bar graph comparing the new quarterly revenue for four sales representatives in a year.
Steps to Draw a Bar Chart
Let’s take an example that you have four different types of fruits: apple, mango, banana, and grapes. These fruits are present in respective numbers 50, 10, 30, and 12.
Now, follow the steps below to easily understand how to draw the bars.
Draw X and Y-axis
Label the Y-axis as “Name of Fruits” and label the X-axis as “Number of Fruits”.
Now, decide the scale range of the data and proceed to draw the bar graphs.
The bars should represent every category along with their numbers.
Tricks and Tips That Can Help You Solve Bar Graphs
Here are some important tricks and tips to help you solve bar graph sample questions.
First of all, read the question carefully and analyse the bar graph. It is important to look at the heading and understand what it says.
Then, analyse the X and Y axis to understand their relationship according to the length of the bars.
Also, it is vital to check the length of the bars.
Practise the drawing of bars and their calculations with bar graph sample questions.
For any confusion, refer to the solved examples of bar graphs.
Do the labelling of every part of the bars carefully.
The implementation of the above tips and tricks helps in understanding how to solve a simple bar chart. It is important to analyse both the x and y-axis and understand how it functions and what it represents.
Conclusion
In summary, a simple bar graph is important in providing a graphical representation of a data set. The bar graph is of two types: horizontal and vertical. One of the important and effective uses of a bar graph is a quick comparison among observations based on one statistical parameter. Each bar graph consists of two axes which are the x-axis and y-axis. One axis is the fixed variable, and the other axis shows the magnitude of the fixed variable. The article sums up steps and various tips on how to solve a simple bar chart and interpret the values with the help of examples.
