l Comparing measures of Central tendency If mean=median= mode the shape of the distribution is symmetric If mode median mean or if mean median> mode the shape of the distribution trails to the right, is positively skewed If mean median mode or if mode> median> mean the shape of the distribution trails to the left is negatively skewed @2002 The Wadsworth GroupComparing Measures of Central Tendency • If mean = median = mode, the shape of the distribution is symmetric. • If mode < median < mean or if mean > median > mode, the shape of the distribution trails to the right, is positively skewed. • If mean < median < mode or if mode > median > mean, the shape of the distribution trails to the left, is negatively skewed. © 2002 The Wadsworth Group
