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 ? Answer - Hottest Day for City X = Monday i.e. 35 Degrees Hottest Day for City Y = Wednesday i.e. 30 Degrees Coldest Day for City X = Sunday i.e. 25 Degrees Coldest Days for City Y = Thursday & Friday Sunday i.e. 25 Degrees each.
