make a bar graph for the given data and answer the question choose a proper scale for that
Answers
Step-by-step explanation:
The marks of a student in different subjects are given below:
Subject Hindi English Maths Science Social science
Marks 43 56 80 65 50
Draw a bar graph from the above information.
ANSWER:
We can draw the bar graph by following the given steps:
Step 1.- On a graph paper, draw a horizontal line OX as x-axis and vertical line OY as y-axis.
Step 2.- Along OX, write the names of the subjects at the points that are taken at a uniform gap.
Step 3.- Choose the scale:
1 big division = 10 marks
1 small division = 1 mark
Step 4.- Heights of the various bars are:
Hindi = 43 small divisions = 4 big divisions and 3 small divisions
English = 56 small divisions = 5 big divisions and 6 small divisions
Maths = 80 small divisions = 8 big divisions
Science = 65 small divisions = 6 big divisions and 5 small divisions
Social Science = 50 small divisions = 5 big divisions
Step 5.- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.

Question 2:
The following table shows the favourite sports of 250 students of a school.
Represent the data by a bar graph.
Sports Cricket Football Tennis Badminton Swimming
No. of students 75 35 50 25 65
ANSWER:
We can draw the bar graph by following the given steps:
Step 1.- On a graph paper, draw a horizontal line OX as x-axis and vertical line OY as y-axis.
Step 2.- Along OX, write the names of the sports at the points that are taken at a uniform gap.
Step 3.- Choose the scale:
1 big division = 10 students
1 small division = 1 student
Step 4.- Heights of the various bars:
Cricket = 75 small divisions = 7 big divisions and 5 small divisions
Football = 35 small divisions = 3 big divisions and 5 small divisions
Tennis = 50 small divisions = 5 big divisions
Badminton = 25 small divisions = 2 big divisions and 5 small divisions
Swimming = 65 small divisions = 6 big divisions and 5 small divisions
Step 5.- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.

Question 3:
Given below is a table which shows the year wise strength of a school. Represent this data by a bar graph.
Year 2011-12 2012-13 2013-14 2014-15 2015-16
No. of students 800 975 1100 1400 1625
ANSWER:
We can draw the bar graph by following the given steps:
Step 1.- On a graph paper, draw a horizontal line OX as x-axis and vertical line OY as y-axis.
Step 2.- Along OX, write the years at the points that are taken at a uniform gap.
Step 3.- Choose the scale:
1 big division = 100 students
1 small division = 10 student
Step 4.- Heights of the various bars:
2011-2012 = 80 small divisions = 8 big divisions
2012-2013 = 97.5 small divisions = 9 big divisions and 7.5 small divisions
2013-2014 = 110 small divisions = 11 big divisions
2014-2015 = 140 small divisions = 14 big divisions
2015-2016 = 162.5 small divisions = 16 big divisions and 2.5 small divisions
Step 5.- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.
We get the following bar graph:
