Unformatted text preview: X = N = 500 (425) = 212,500 New = (212,500 100) / 499 = 425.65 4. Base on the following graph: What is the range? _______________ 9 1 + 1 = 9 What is the median? _______________ 1, 1, 2, 2, 2, 2, 3, 3, 7 , 7, 8, 8, 8, 8, 9, 9, Median position = (16 + 1) / 2 = 8.5 Median = (3 + 7) / 2 = 5 5. In a population with a mean of = 4.05, a score of X = 1.50 would have a deviation score of __________. X = 1.50 4.05 = 5.55 2 6. A population has SS = 36 and = 3. How many scores are in the population? ____________ N = 36 / 3 2 = 4 7. A sample of n = 7 scores has SS = 42. What is the standard deviation for the sample? ____________ SD = (42 / (71)) = 7 = 2.65 8. What is the variance for the following population of scores? ____________ Scores: 75, 75, 72, 76, 77, 76, 74 3...
