# Question

Consider the following set of data:

(a) Draw a scatter diagram of the data and compute the linear correlation coefﬁcient.

(b) Draw a scatter diagram of the data and compute the linear correlation coefﬁcient with the additional data point (10.4, 9.3). Comment on the effect the additional data point has

on the linear correlation coefﬁcient. Explain why correlations should always be reported with scatter diagrams.
