Statistics right skewed
WebFeb 3, 2024 · The skewed distribution is when data in a chart lean either to the left or the right side of the scale, resulting in a nonsymmetrical curve. This occurs in different statistical data sets, including frequency distributions. Any distribution with its left side shaped differently than its right side is a skewed distribution. WebA distribution is skewed right if it has a longer tail on the right side (higher values) and skewed left if it has a longer tail on the left side (lower values). A uniform distribution has equal frequencies across all age groups. In our case, to assess the skewness, we compare the mean and median of the distribution. The mean is given as 39.88.
