Exercise 9 Page 494

Where does the distribution tail extend to?

Skewed left

Practice makes perfect

We can use dot plots and histograms to identify the shape of distributions.

The distribution is skewed left if the tail of the graph extends to the left and most of the data are on the right.
The distribution is skewed right if the tail of the graph extends to the right and most of the data are on the left.
The distribution is symmetric if the left side of the graph is a mirror image of the right side of the graph.

Now, consider the given histogram.

Most of the data values are on the right and the tail extends to the left. This means that the distribution is skewed to the left.
