Double Bar Graphs

Double Bar Graphs We can use the double bar graphs to compare or present more than one kind of information by using bars. We can also call the Double bar graphs as double bar charts. We have some important points to draw double bar graphs. Those are We need to decide which title we can give to graph We need to decide what kind of bars we can take (horizontal or vertical bars) given We need to choose a proper scale (To give the proper scale, we need to find the difference of the numbers which are in table, then from that, we can take the scale) We need to put the labels to x and y axis Next, from the given information, we need to draw the bars with the using of scale which we have taken in the third step. Example1:Construct the double bar graph with using of below table.We can use the double bar graphs to compare or present more than one kind of information by using bars.

Example1:Construct the double bar graph with using of below table. Solution: Step1: We need to decide which title we can give to graph We have the title from table that is Scores in practice test and test of students Step2: We decided to take vertical bars Step3: Since the scores are differ from one another by 5, 10, 15 0r 20 So, we can take scale of 10 If the differences are like 2, 4, 6 We can take scale of 2 Step4: we can label the x axis with students names Y axis with scores Step 5: Finally, from the given information, we need to draw the bars
