Document Summary

Exercise 2 & 3 due in tutorial today. Last week"s lecture u required reading: levin et al. 3 & 4: measures of central tendency, mean, median and mode, measures of dispersion, range, mean deviation, variance, standard deviation. Skewed distributions: for a positive (right) skew, the mean will be greater than the mode and median. Means, medians, and modes in. Skewed distributions: for a negative (left) skew, the mean will be less than the mode and median. Measures of variability u variability measures u the range u mean deviation u variance and standard deviation. Just like the mean deviation but instead of using absolute values we. Square the deviations to avoid negative scores u the standard deviation is the square root of the variance: Take the square root so not talking about squared units of measurement (i. e. , squared dollars, squared hours) Sum of squares (numerator of standard deviation)
