Errata for Math Mammoth Statistics & Probability

This list of errors concerns Math Mammoth Statistics & Probability book.

Date: November 1, 2014

Error: The definition of skewed distribution was reversed (left versus right). The text presented a left-skewed distribution as an asymmetric distribution where the "bulk" of the data is on the left; in reality, a left-skewed distribution has a tail that is on the left, and the bulk of the data is on the right. The answer key reflected the same error in several places.

This affects: Several lessons in the book and their answer keys in Edition 3.0, sold up till October 31, 2014.

Corrected edition: 3.1, available from November 1, 2014 onward.
