1. Given the following set of 25 numbers, fill in the blanks below: (8 points; 2 for each blank) 98 96 94 92 88 88 88 88 86 84 84 84 82 78 78 76 72 70 68 66 66 66 62 58 56 What is the arithmetic MEAN (round to two decimals): What is the MEDIAN: What is the MODE: What is the RANGE: 2. Given the following information, fill in the blanks wherever you find one. HINT: Use Page 300, Figure 11.3 A. as a guideline; we've done it in class. (22 points; 1 for the first 10; 4 for the last 3) Question 2 is not related to Question 1; data are different. (score - mean (score - mean) squared Scores Deviation Scores Deviation Scores Squared 88 22 84 18 84 324 70 16 70 4 66 0 60 50 48 324 40 676 XE Sum of Squares= (means E(X - X)? VARIANCE (or Sum of Squares divided by number) (round to 2 decimals if necessary) =3. Using our data from number 2 above: (15 points; 3 for each blank) What is the" standard deviation"? HINT: How to find standard deviation is on page 301. Standard Deviation = (round to two decimal points) What would be the score at -2 Standard Deviations: (round to a whole number) What would be the score at +1 Standard Deviation: (round to a whole number) ***HINT: The two scores above are not necessarily scores that exist on the list; your answer should be what the score WOULD be at the levels asked. What would be the "z-score" for a score of 84 (round to two decimals): HINT: z-score formula is on page 301 and explained first paragraph on 302. What would be the "z-score" for a score of 50 (round to two decimals)
