Interpretation of Bar Graphs
The first step in reading a bar graph is to know what it represents or what is the information given by it.
For this, we read the titles which are generally written just below the hor izontal line (X-axis) and
ad ja cent to ver ti cal line (Y-axis). Af ter know ing that what does a bar graph rep re sent, we read the scale so
that we can know the pre cise val ues in the given data.
After reading a bar graph one must be able to draw certain conclusions from it. Drawing some conclusion
from a given bar graph means interpretation of the bar graph.
EX AM PLE 3. Read the bar graph shown and an swer the fol low ing ques tions:
