Question

Which of the following would you use if you had to represent average rainfall for one week in Bangalore.
a. line graph
b. Bar graph
c. Double line graph
d. Double bar graph

Answer 1

Hint: In this question, we are asked to choose a graph that will best represent the average rainfall for one week in Bangalore.
Firstly, we need to understand that representation of average rainfall includes fractional data also.
Therefore, we should see which graph could best represent this and use another graph in a representation like Line graph, Bar graph, Double line graph, Double bar graph.

Complete answer:
A line graph is a graph that is used to represent the change in a quantity for another quantity. This graph is used to represents data between two changing quantities with a line that joins a series of successive data points.
The bar graph helps to compare the different types of data among different groups. it shows the major changes in data over time. It can also represent fractional data as well whole number data.
A double line graph is used for representation as well as the comparison between the growth of two trends. They represent the variation of one quantity for another quantity.
The Double bar graph is used to represent and compare data among items based on two categories at the same time.
The bar graph is plotted between the temperature of the state. Also, it has data between maximum and minimum rainfall during the rainy season for a week. It is used by the metrological department for major changes in data over time.

Therefore, option b.BAR GRAPH is the correct answer.

Note:
According to the above situation, the Bar graph is best for the representation of average rainfall for one week in Bangalore.
Line graphs are inconvenient if you have to plot fractions or decimal numbers same applies to other graphs too.
Therefore, Line graph, double line graph, double bar graph, is not perfect for this kind of representation.
