Graphs

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

A bar graph uses bars to compare different categories of data.

A line graph shows how data changes over time by connecting points with a line.

A pie chart is a circular graph that shows parts of a whole, with each slice representing a category.

To read a graph, look at the labels on the axes, the title, and the data points to understand the information.

'More than' indicates a greater quantity compared to another value shown in the graph.

'Fewer than' indicates a smaller quantity compared to another value shown in the graph.

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.

A data point is a specific value plotted on a graph that represents information.
