-
Histogram of a sample from a normal distribution – it looks fairly symmetric and unimodal

-
Normal probability plot of a sample from a right-skewed distribution – it has an inverted C shape.
-
Histogram of a sample from a right-skewed distribution – it looks unimodal and skewed right.

-

“Histories are more full of examples of the fidelity of dogs than of friends.”
