Another measure of variation is the mean absolute deviation. It is computed using the formula
Compute the mean absolute deviation of the data in Problem 11 and compare the results with the sample standard deviation.
Answer to relevant QuestionsKarl Pearson developed a measure that describes the skewness of a distribution, called the coefficient of skewness. The formula is Skewness = 3(mean — median) /standard deviation The value of this measure generally lies ...Explain how standard deviation measures spread. In your explanation include the computation of the same standard deviation for two data sets: Data set 1:3,4,5; Data set 2:0,4,8. The following data represent the number of live multiple-delivery births in 2007 for women 15 to 54 years old. Age ..... Number of Multiple Births 15–19 ..... 100 20-24 ..... 467 25–29 .... 1620 30-34 ...The following data represent the male and female population, by age, of the United States in 2008. (a) Approximate the population mean and standard deviation of age for males.
