In a positively skewed distribution, there’s a cluster of lower scores and a spread out tail on the right. The direction of this tail tells you the side of the skew One side has a more spread out and longer tail with fewer scores at one end than the other. In skewed distributions, more values fall on one side of the center than the other, and the mean, median and mode all differ from each other. The mean, median and mode are all equal the central tendency of this data set is 8. From looking at the chart, you see that there is a normal distribution. Example: Normal distributionYou survey a sample in your local community on the number of books they read in the last year.Ī histogram of your data shows the frequency of responses for each possible number of books. The mean, mode and median are exactly the same in a normal distribution. Most values cluster around a central region, with values tapering off as they go further away from the center. In a normal distribution, data is symmetrically distributed with no skew.
