How to describe a right skewed histogram
WebMar 1, 2024 · Let’s now take a look at the third distribution – a histogram that’s heavily skewed to the right. As we have expected, the distribution’s peak (or its mode) will lie within the lower end of the range. When the distribution is positively skewed, we also expect that the mode has the least value among the three central measures. 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.

WebThe histogram shows a very asymmetrical frequency distribution. Most people score 20 points or lower but the right tail stretches out to 90 or so. This distribution is right skewed. If we move to the right along the x-axis, we go from 0 to 20 to 40 points and so on. So towards the right of the graph, the scores become more positive.
