Give an example of data analysis that a bar chart is the best choice to visualize the data.

Answer 1

Solution: The bar graph is a graphical technique to represent data using the bars of different heights or lengths. The bar graphs are used to visualize the categorical data.

For example, A company sells four models of one car. The sales of these four variants in the past 2 months is given below:

Model	Number of cars sold
SUV	35
MPV	42
Hatchback	62
Sedan	38

Since the data is categorical, therefore, we can visualize this data using the bar graph. The bar graph is given below:

Bar Graph 62 50 42 38 40 g 30 Z 20 10 0 SUV MPV Hatchback Sedan Model
