Chapter 1, Problem 8STP

To determine

The correct option to be chosen.

Answer to Problem 8STP

The correct option is (D).

Explanation of Solution

Introduction:

Data can be represented in various forms namely line graphs, bar graphs, circular graphs and pictographs. To represent comparative data, bar graph is the most suitable. To represent data as a part of a whole, circular or pie graphs are used. To illustrate broad differences between categories, pictographs are used and to illustrate changes of continuous variables over time line graphs are used.

In order to represent relationship between dependent and independent variables change over time, line graphs are the most suitable.A line graph is used to illustrate the relation between two scale variables. Line graphs are mostly used for continuous data and the data of the independent variables are an increment of time.

Conclusion:

Hence, the correct option is (D) line graph.
