WebMay 19, 2024 · Skewness is a way to describe the symmetry of a distribution. A distribution is negatively skewed if it has a “tail” on the left side of the distribution: Note: Sometimes negatively skewed distributions are also called “left skewed” distributions. In this article we share 5 examples of negatively skewed distributions in the real world. WebThe mean is 7.7 7.7, the median is 7.5 7.5, and the mode is seven. Of the three statistics, the mean is the largest, while the mode is the smallest. Again, the mean reflects the skewing the most. To summarize, generally if the distribution of data is skewed to the left, the mean is less than the median, which is often less than the mode.
WebPEAKS: Graphs often display peaks, or local maximums. It can be seen from the graph that the data count is visibly higher in certain sections of the graph. 1. one clear peak is called a unimodal distribution. 2. two clear peaks are called a bimodal distribution.
