**Talk Math** How are line plots the same or different than bar graphs or picture graphs?

Answer: Bar graphs display data in a way that is similar to line graphs.

Line graphs are useful for displaying smaller changes in a trend over time. Bar graphs are better for comparing larger changes or differences in data among groups.

A picture graph, or pictograph, is a graph used to display information that uses images or symbols to represent data.
