Left-skewed distribution tail direction.

Explanation:
The main idea is that skew direction is named by where the long tail extends. In a left-skewed distribution, the tail runs to the left, toward smaller values. Most data cluster toward higher values, with a few unusually small observations stretching the tail to the left. This is also why the mean tends to be pulled down relative to the median in left-skewed data. So, the tail is on the left, making the left tail the correct description.
