Ch.2 and Ch.3 Practice Problems Chapter 2: 11. For the following courses, take note the (a) mean, (b) normal, (c) pump of work disagreements, (d) version, and (e) modular remainder:2, 2, 0, 5, 1, 4, 1, 3, 0, 0, 1, 4, 4, 0, 1, 4, 3, 4, 2, 1, 0 X| (X = X)^2| 0| 4| 0| 4| 0| 4| 0| 4| 0| 4| 1| 1| 1| 1| 1| 1| 1| 1| 1| 1| 2| 0| 2| 0| 2| 0| 3| 1| 3| 1| 4| 4| 4| 4| 4| 4| 4| 4| 4| 4| 5| 9| 42| 56| a.)Mean: 42/21=2 b.)Median: 2 c.) entirety of upstanding differences: 52 d.) Variance-2.47 e.) Standard Deviation- 1.57 To take the tell of quaternsquare up deviation subtract the mean from separately gain which will give you each scores deviation score whence square each of these scores. Add up the squared deviation scores and you have the sum of squared deviation scores. assort the sum of the squared deviation scores by the count of scores and you will have the variance. The square sink of the variance is the model deviation. 12. For the following scores, find the (a) mean, (b) median, (c) sum of squared deviations, (d) variance, and (e) standard deviation: 1,112; 1,245; 1,361; 1,372; 1,472 a.) Mean: 1312 b.) Median: 1361 c.

For the following scores, find the (a) mean, (b) median, (c) sum of squared deviations, (d) variance, and (e) standa rd deviation: 3.0, 3.4, 2.6, 3.3, 3.5, 3.2 ! a.) mean: 3.16667 b.) median: 3.25 c.) sum of squared deviations = ? d.) variance = (0.32660)^2 = 0.10667 e.) standard deviation = 0.32660 16.
