Number of activity kits sold in the month of June = 22
Number of activity kits sold in the month of July = 14
Number of activity kits sold in the month of August = 18
Therefore, total number of activity kits sold in these five months
= 16 + 10 + 22 + 14 + 18 = 80.
Drawing a bar graPh
Let us draw a bar graph using the following data which shows the number of students
using various modes of transport to reach school.
Modes of transport Walking Bicycle School Bus Car
Number of students 20 15 35 10
To draw a bar graph for the given data, we follow the steps given below.
Step 1: Draw a horizontal line (X-axis) and a vertical
line (Y-axis) which are perpendicular to Modes of Transport Used
each other on graph paper. by Students
Step 2: Take a suitable scale on the vertical line
(Y-axis) such as 1 unit = 5 students.
Step 3: Now, using the scale, mark the number of Number of students
students on the Y-axis such as: 5, 10, 15,
20, 25, 30, 35, 40, 45 and 50.
Step 4: On the horizontal line (X-axis), mark the
different modes of transport at equal Modes of Transport
distances.
Step 5: Draw bars of equal width that represent the number of students.
Step 6: Give the bar graph an appropriate title.
Be Aware
While drawing a bar graph:
The title of the graph should be written at the top of the graph.
The items represented on the horizontal and vertical lines should be written along the lines.
A convenient and clear scale should be used.
Bars should be drawn of equal width and at equal distances.
Bars should be shaded or coloured.
Teacher’s Explain to the students how to choose a scale for data (numerical values) and why and how the least and the
Tip greatest numerical values are important. Also, tell the students repeatedly that a vertical bar graph uses a
horizontal axis for the labels. Explain that we can also draw a horizontal bar graph using the vertical axis for
the labels and mark the numerical values on the horizontal axis.
