Exercise No. 4 Measures of Variability 1) Given the measurements 20, 26, 40, 39, 25, 36 and 34, compute for the a) range, b) Mean deviation, c) standard deviation and variation. 2) Workers A and B are assigned to the same job. Worker A can finish his job in 7 hours, with a standard deviation of 8. Worker B can finish the same job in 6.5 hours with a standard deviation of 10. Who is more consistent? 3) Below is the frequency distribution showing the result of an IQ test of a group of students in a certain university: Classes 80-85 86-91 92-97 Frequency (f) 2 4 5 98-103 7 104-109 12 110-115 9 116-121 7 122-127 4 Compute for MD, SD, Variance, and Q 32 Exercise No. 4 Measures of Variability 1) Given the measurements 20, 26, 40, 39, 25, 36 and 34, compute for the a) range, b) Mean deviation, c) standard deviation and variation. 2) Workers A and B are assigned to the same job.
