A frequency distribution that has a "tail" extending to the left with most of the data on the right side of the distribution has a skew. normal negative rigN left

negative

Step-by-step explanation: Frequency distributions are often described based based on the level of symmetry. Symmetrical distributions are characterized as exhibiting a bell-shaped curve with large portion of the distribution stationed in the middle. Other distributions may be assymmetrical with large concentration either to the left or right, this is called skewness. Distributions with a left tail and values mainly concentrated on the right are called negatively skewed or left skewed while those with extending right tail with values concentrated on the left are called positive or right skewed distribution.
