Diagrammatic representation of data
Diagrammatical Representation of Data
Representation of any numerical data by using diagrams is known as diagrammatic representations.
- Line Diagrams
In the linear diagrammatic representations of the data, we will use the line that connects the points of various data in the graph by taking two variables on horizontal and vertical axes.
Example:
The below diagram gives the linear representation of the wildlife population of bears, whales, dolphins.
2. Bar Diagrams
In the bar diagrammatic representation of data, the data can be represented by rectangular bars. The height of the bars gives the value or frequency of the variable. All rectangular bars should have equal width. This is one of the best-used tools for the comparison of the data.
Example:
Birthdays of different students at the school in the different months.
3. Histograms
Histograms are also similar to bar diagrams; they use rectangular bars to represent the data. But all the rectangular bars are kept without any gaps.
4. Pie Diagrams
Pie Diagram is a diagrammatic representation of data by using circles and spheres. In the pie diagrams, a circle is divided into parts, such that each part shows the proportion of various data.
Example:
The below pie diagram represents the different modes of transport used by the students.
5. Pictographs
The pictographic representation shows the given data graphically by using images or symbols.
Example:
The pictograph diagram below shows the mode of transport used by the number of students using the image, and each image represents the value.
