PIE GRAPHS AND LINE GRAPHS

A pie graph is a circular chart divided into slices to illustrate numerical proportions. Each slice represents a category's contribution to the whole.

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is used to show trends over time.

To read a pie graph, look at the size of each slice to understand the proportion of each category compared to the whole.

To read a line graph, observe the points plotted on the graph and the lines connecting them to see how values change over time.

The total of all slices in a pie graph equals 100%, representing the whole.

Graphs are used to visually represent data, making it easier to understand trends, comparisons, and relationships.

The x-axis typically represents the independent variable, often time, showing how it affects the dependent variable on the y-axis.

The y-axis represents the dependent variable, showing the values that change in response to the independent variable on the x-axis.

A category in a pie graph refers to a specific segment of data that contributes to the whole, such as types of pets or favorite foods.

The most popular option in a pie graph is represented by the largest slice.
