Question

In an appropriate regression model, the normal probability plot should appear as a random scatter of points.

True or false?

Answer 1

Answer: False

----------------

Solutions / Discussion:

In the points in a normal probability plot fall around a positively sloping diagonal line, it suggests that the data is possibly normally distributed.

So, the specific pattern that we are looking for is the points to fall around a positively sloping diagonal line. If they do, we can conclude that the data is possibly normally distributed.

Curvature and/or outliers suggest that the data is NOT normally distributed.
