Grouping the observations

Rather than focusing on individual neighborhoods, we may group the neighborhoods by the borough they are located in and plot the points using different symbols and colors.

  1. On the Biplot task pane, click Vary point color / symbol.
  2. In the Group / Color / Symbol drop-down list, select Borough.
  3. Click Recalculate.
    The results are calculated and the analysis report opens.

It is easy to see that the neighborhoods in The Bronx are more affordable than those in Manhattan and that they have lower scores for shopping & services, transit, food and creative. The axes are labelled on the edge with higher values for convenience.
