Self-Check 2
  1. Describe the correlation for each of the following scatterplots.
    1. This scatterplot shows points that roughly follow a line falling from upper left to lower right with one point that is far from this grouping.
    2. This scatterplot shows points that are randomly placed.
    3. This scatterplot shows points that roughly follow a line rising from the lower left to the upper right.

      Answer

  2. From the scatterplots shown, is there one (or more) that has an outlier? Answer

You have now had some practice in determining and interpreting a line of best fit. When one or two outliers are present, they normally don’t have an effect on the line of best fit.
