Line graphs

Some line graphs use a false origin. A false origin allows the vertical scale to start at a different value.

Scatter plot

Scattergraphs are used to represent and compare two sets of data. (Bi-variate data)

By looking at a scattergraph, we can see whether there is any connection (correlation) between the two sets of data.

Types of correlation
