Skewed bimodal distribution

WebbCentral Tendency in Skewed Distributions • Mean, influenced by extreme scores, is found far toward the long tail (positive or negative) • Median, in order to divide scores in half, is found toward the long tail, but not as far as the mean • Mode is found near the short tail. • If Mean – Median > 0, the distribution is positively skewed. • If Mean – Median < 0, the … Bimodal distributions are a commonly used example of how summary statistics such as the mean, median, and standard deviation can be deceptive when used on an arbitrary distribution. For example, in the distribution in Figure 1, the mean and median would be about zero, even though zero is not a typical value. The standard deviation is also larger than deviation of each normal distribution.
