Question

What are the signs that a residual plot shows a line of best fit ?
i) The residual values are distributed in a clear pattern on both sides of the y-axis.
ii) The residual values are randomly distributed on either side of the x-axis.
iii) The residual values are randomly distributed on either side of the y-axis.
iv) The residual values are clustered close to the x-axis.

  1. i
  2. ii
  3. iii  and i
  4. ii and iv

The correct answer is: ii and iv


    the signs that a residual plot shows a line of best fit is
    The residual values are randomly distributed on either side of the x-axis.
    The residual values are clustered close to the x-axis.
