Reading & Interpreting Graphs

A graph is a visual representation of data that shows relationships between different quantities.

The x-axis is the horizontal line on a graph that usually represents the independent variable.

The y-axis is the vertical line on a graph that usually represents the dependent variable.

You add the heights of the bars together to find the total.

Interpreting a graph means understanding what the data represents and drawing conclusions from it.

A bar graph is a chart that presents categorical data with rectangular bars representing the values.

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments.

The title explains what the graph is about and what data is being represented.

You look for the tallest bar, which represents the category with the most votes.

It means that the category represented by that bar has a value of 22.
