Question

To show the relationship between two variables in a dataset, which of the following chart(s) can be used?

• A. line graph
• B. scatter plot
• C. both (a.) and (b.)

Answer 1

The correct option is C both (a.) and (b.)

A scatter plot uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point.

A line graph is used to show data that changes over time. All the data points are connected by a line.

Example: Below charts represent the weight of a group of people with respect to their age.
From both the graphs, we can colclude that the weight of the people increases with respect to their ages.

Hence, both the line graph and scatter plot can be used to show the relationship between two variables in a dataset.

Option (c.) is the correct choice.
