Line Graphs

Line graphs are a powerful data visualization tool that displays the relationship between two variables on a cartesian coordinate system. It uses lines to connect data points that show trends, patterns, and changes over time. Line graphs questions are usually asked in the form of question sets.

Real-Life Applications of Line Graphs

Real-life examples where the concept of line graphs is involved are:

Application 1: Economic Indicator Representation

Line graphs are commonly used to analyze economic indicators, such as GDP growth, unemployment rates, stock market trends, or inflation rates.

Application 2: Sales Data Analysis

Line graphs help track sales performance, marketing campaign effectiveness, or customer trends, assisting in decision-making and strategy formulation.

Application 3: Cricket Stats

Line graphs can be used to show the run rate progression of a cricket team during an inning.
