Step 1 of 3

February 6, 2019 Week 3, lecture 2 Mean and standard deviation -shows the center and spread of data -measured by the median, quartiles, and percentages Sample: ( ) piece of the whole population Population: (μ) larger group Sample of standard deviation (s) Population standard deviation (σ) Calculating sample of standard deviation (s) Xi (data) 2 Xi- (Xi- )​ 10 -20 400 20 -10 100 30 0 0 40 10 100 50 2- 400 Total = 1000 (average) = 30 n = 5 (# of data points) n-1 = 4 √1000/4 = √250 = 15.8 Variance: the square of the deviation; in this case = 250 -75% of data falls within 2 s.d. of the mean -Histograms “bell shaped” 95% falls within 2 s.d. of the mean If mean = 79, and s.d. = 13, Then the intervals = 79 + 2(13) = 105 and 79 - 2(13) = 53
