A histogram that has a long tail due to outliers in the lower portion of the dataset is known as what type of distribution?

A histogram featuring a long tail in the lower portion of the dataset signifies that the distribution is left skewed. This type of distribution is characterized by a concentration of values on the right side, with fewer values extending to the left. Consequently, the mean of the dataset is typically less than the median due to the influence of the outliers in the lower range.

In left-skewed distributions, as the frequency of data decreases with decreasing values, the tail points towards the lower end of the scale. This means there are fewer extreme low values, which is the defining factor of left skewness. Understanding this concept is crucial in analyzing data patterns and assessing the distribution of values within a dataset.
