The types of bar diagrams commonly discussed in class 11 statistics include several variations designed to represent data effectively.
Types of Bar Diagrams
While basic bar graphs can be either vertical or horizontal, more complex types provide additional insights. According to the provided reference, these include:
-
Grouped Bar Graph: Also known as a clustered bar graph, this type is used to compare multiple categories across different groups. For example, you could compare sales figures for different products across different regions using a grouped bar graph.
-
Stacked Bar Graph: This type represents data as different segments within the same bar. Each segment represents a different category, and the total height of the bar represents the overall total. An example could be showing the composition of a company's revenue by product line, with each product line contributing a segment to the total revenue bar.
Here's a table summarizing the types of bar diagrams:
| Type of Bar Diagram | Description | Example |
|---|---|---|
| Vertical Bar Graph | Bars are displayed vertically, with the length of the bar proportional to the value. | Comparing the population of different cities. |
| Horizontal Bar Graph | Bars are displayed horizontally, with the length of the bar proportional to the value. | Ranking customer satisfaction levels for different services. |
| Grouped Bar Graph | Compares multiple categories across different groups. | Comparing sales of multiple products across different regions. |
| Stacked Bar Graph | Represents data as segments within the same bar, showing the composition of a whole. | Showing the composition of a company's revenue by product line. |
