A scatter plot can be used for data in the form of ordered pairs of numbers. The result will be a bunch of points "scattered" around the plane.
If the general tendency is for the points to rise to the right of the graph, then we say there is a positive correlation between the two variables measured. If the points fall to the left of the graph, we say there is negative correlation. If there is no general tendency, then there is no correlation.
If the tendency is not very pronounced - that is, the points are scattered widely - then we say the variables are weakly correlated. If the correlation is more pronounced, we say the variables are strongly correlated.
Draw a scatter plot for the following data about different bird species.
Explain whether there is a positive correlation, a negative correlation, or no correlation between the sets of data in the scatter plot.
