## RS Aggarwal Solutions Class 7 Maths Chapter 22 Exercise 22.2 PDF – “Bar Graph Definition”

The Bar Graph is the depiction of the grouped data in the form of the horizontal or the vertical bars which is its pictured representation to make it more understandable and visual. Here, in the bar charts, the length of the bars drawn is equivalent to the measurement of the data.

We can say that the Bar graphs are the type of data handling tools in the field of statistical studies. As we all knew that this is exactly what we do in statistics i.e., grabbing the data, presenting, doing the analysis, organizing it, and finally doing the translation of the observations made by the data. This is what we meant by the term statistics. We can represent such kind of data using the bar graphs, histograms, in tabular formats, pie charts, polygons, etc.

### RS Aggarwal Solutions Class 7 Maths Chapter 22 Exercise 22.2 PDF – “Types of Bar Charts”

We have mentioned the different type of Bar Graphs below, please read them carefully –

**1. Vertical Bar Graphs –**

We can define the Vertical Bar Graphs as vertically representing the grouped data with the help of a chart or a graph using the bars. Here, the bars denote the exact measurement of the specific data. Also, we represent such data in the y axis part of the chart or the graph, and the height of the bars here denotes the total value of the particular taken data.

**2. Horizontal Bar Graphs**

We can define the Horizontal Bar Graphs as the Horizontally representation of the grouped data with the help of a chart or a graph using the bars. Here, the bars denote the exact measurement of the specific data. Also, we represent such data in the x-axis part of the chart or the graph used and the height of the bars here denotes the total value of the particular taken data.

**3. Grouped Bar Graph**

We can define the Grouped Bar Graphs as a step graph that is being used for doing the discrete value representation. This is for the multiple objects which are lying under the same group or the same category. Here, we combine the total number of the data into a single bar. Here, in short, we perform the comparison between the different sets of the data.

**4. Stacked Bar Graph –**

We can define the Stacked Bar Graphs as the graph dividing the one aggregated data into multiple segments which are further represented using the different colors used to depict the specific category. Here, in the Stacked Bar Graph, the bar lines themselves is the depiction of the whole while each of its segment is the depiction of the varied parts of the whole.

**RS Aggarwal Solutions Class 7 Maths Chapter 22 Exercise 22.2 PDF – “Frequently Asked Questions – Bar Graph”**

**1. Describe the meaning of the Bar Graph in simple words?**

The Bar Graph or the Bar Chart or the Bar Diagram can be described as the graph which by making use of the rectangular bars depicts the categorical data. Moreover, the Bar Graph also portrays the similar and dissimilar points within its multiple varied categories.

**2. Name the multiple types of Bar Graphs?**

Below we have mentioned the multiple types of Bar Graphs –

- Horizontal Bar Graph
- Vertical Bar Graph
- Stacked Bar Graph
- Grouped Bar Graph

**3. When do we use the Bar Graph?**

We generally use the Bar Graph when we need to do the comparison of the items within the multiple groups in a time. The Bar Graph is best to use when you encounter a situation, where the changes are quite bigger.

**4. What is the best situation in which a horizontal bar chart can be used?**

You can make the horizontal bar graph your first choice when you need to plot the nominal variables in your chart.

**5. What is the best situation in which a vertical bar chart can be used?**

The most frequently used bar chart is the “Vertical Bar Graph”. It can be best used in the case of plotting the ordinal values.
