Calculate the covariance for the following four pairs of data: .
Consider a small data set with three pairs of observations: . Find the covariance of this data set.
If most points in a scatter plot lie in the Top Left Quadrant (TLQ) and the Bottom Right Quadrant (BRQ) relative to the mean point, the covariance will most likely be:
True or False: If the Pearson correlation coefficient between two variables is , it guarantees that there is no relationship of any kind between the variables.
True or False: A scatter plot that has a very steep line of best fit will always have a correlation coefficient closer to 1 than a plot with a shallow line of best fit.
