Name: Score: Section: Date: Activity 4 Skewness 1. Determine the coefficient of skewness for each of the following sets of data and describe the result. a. x = 50 x = 40 s = 4.5 b. x = 100 = 120 S = 11.5 C. X = 75 X = 85 s = 6.2 d. x =295 * = 250 S = 35 2. At Saint Mary's Academy, the mean age of the students is 19.2 years, with a standard deviation of 1.2 years. The median age is 18.6 years. Compute the coefficient of skewness. Describe the skewness.Name: Score: Section: Date: Activity 3 Coefficient of Variation 1. A random sample of 10 students in a Statistics class got a mean score of 78% with a standard deviation of 7% and a mean weight of 105 pounds with a standard deviation of 10 pounds. Determine the coefficient of variation. 2. In a barangay health center with no more than a hundred patients, a distribution of two different units is given to compare the dispersion of weights with the dispersion of heights. The mean height is 5.7 feet with a standard deviation of 0.9 feet and the mean weight is 72.5 kilograms with a standard deviation of 8.1 kilograms. 3. Two employees A and B are to compare their daily routine of work. A can finish his job with an average of 1.5 hours with a standard deviation of 0.025 hour, whereas B can finish the job with an average of 4 hours and a standard deviation of 0.01 hour. Who is more consistent? 4. A dealer of an electronic adaptor sells two classes of adaptor, A and B. Adaptor A has a mean life span of 2 100 hours with a standard deviation of 150 hours, while Adaptor B has a mean life span of 2 600 hours with a standard deviation of 200 hours. Which adaptor has the greater relative dispersion? Which is more consistent? SKEWNESS
