Bar Graphs Used to compare amounts, or quantities The bars provide a visual display for a quick comparison between different categories

Line Graphs Used to show correlations, or relationships between the variables The line or lines show the change that occurs over time or the change that results from increasing the independent variable

Graphs Graphs are scientific tools that provide a visual, or image, of the collected data Graphs help us observe trends, make predictions, and identify relationships
