## Double Bar Graph

 Pictograph Bar Graph Double Bar Graph Histogram Pie Graph Line Graph Difference between Bar Graph and Histogram

We hope that you are familiar with Bar Graph and if not, this topic is already here Bar Grap

A single or simple bar graph usually represents value to a single set of data. But when we need to represent and compare two sets of data, we need Double Bar Graphs.

Following example further illustrates Double Bar Graphs.
Example - Temperature of two cities X & Y for entire week is represented in the following tabular form.

 Temperature Mon Tue Wed Thu Fri Sat Sun City X 27 28 30 31 29 31 27 City Y 30 29 30 29 28 32 28

Draw a double bar graph and answer the following questions:<

1) On which day the temperature of both cities is same ?

2) On which day there is maximum difference in temperature of both cities ?

3) On which day there is least difference in temperature of both cities ?

4) Hottest and coldest days(s) for both cities ?

Answer - Below is the required Double Bar Graphs representing temperature of City X and City Y from Monday to Sunday:

## Below are answers to questions:

Question 1 - On which day the temperature of both cities is same ?
Answer - The temperature of city X and Y is same on Wednesday i.e 30 degrees

Question 2 - On which day there is maximum difference in temperature of both cities ?
Answer - Maximum difference in temperature of both the cities is on Thursday i.e. 7 degrees difference

Question 3 - On which day there is least difference in temperature of both cities ?
Answer - Least difference in temperature of both the cities is on Tuesday i.e. 1 degree difference only.

Question 4 - Hottest and coldest days(s) for both cities ?
