Scatterplot


(scatex.gif on the list)

A scatterplot is a type of diagram that displays data on a graph that plots individual data points with the X axis and Y axis. A certain set of patterns can be displayed when all the data points are plotted. If all the points are plotted across the graph with no discernible pattern then there no correlating pattern among the points. If all the points follow closely together from the bottom left of the map to the top right then it shows a strong positive correlation while if all the points are close together starting from the top left towards the bottom right then there's a strong negative correlation. Weak positive and negative correlations are similar to graphs with no correlation where if the points weren't following a strict diagonal direction then there'd be no correlation between the points. The image shown above is a scatterplot that shows a strong positive correlation between the price of diamonds in carats and size of diamonds in carats.
