Pictorial Representation of Data
In pictorial representation symbols or images are used to represent a specific number of objects. Pictorial representations are of different kinds such as Bar graphs, Line graphs, Pictographs, etc.
Types of Pictorial Representation
Here we will discuss the types of pictorial representations and examples of pictorial representations.
A bar graph presents the categorical data with vertical bars with lengths proportional to the values that they represent. Bar charts can be two types 1. Vertical bar charts 2. Horizontal bar charts. The other name for vertical bar charts is called Column bar charts.
A bar graph is used for the comparison of discrete categories. On one axis it shows the different categories being compared and the other axis represents the measured value. The height or length of the bars specifies the value of the variable.
Example of Bar Graph
A Mobile company manufactures three different models of mobiles. The sales of the mobiles for the months are shown in the table. Represent it using the bar chart.
The X-Axis represents the Months and Y-Axis represents the sales.
|Month||Mobile1||Mobile 2||Mobile 3|
In this method, the data is displayed in a circular graph. The pieces of the circle represent different categories. The pieces are proportional to the fraction of the whole in each category. In other words, each slice of the pie is comparative to the size of that category in the group as a whole. The entire “pie” is taken as 100 percent of a whole, while the pie “slices” represents portions of the whole. By using this pie chart same data can be represented in different sizes.
Here the pie chart displays the data of the favorite activities. Out of 100 percent 40 percent like walking, 24 percent like cycling, 18 percent like swimming, 12 percent like golf, and other activities are liked by 6 percent.
A line chart or Line graph is a type of chart the information is displayed as a series of data points connected by straight line segments. It shows Quantitative values over a specified time. It is used in many fields. We can see the trend in the data over intervals of time. Line charts display shorter changes and better than bar graphs for the aspect. It is used in showing the recurring data to facilitate comparison.
In this method, the data is represented using images. It represents the frequency of data by using symbols or images. It is very easy to understand. It is one of the simplest ways to represent data.
