Calculate SS, variance, and standard deviation for the following population of N = 8 scores:
1, 3, 1, 10, 1, 0, 1, 3
(Note: The computational formula works well with these scores.)

Samples of the age in years of student cars and faculty/staff cars: Student: 10,4, 5, 2,9,7, 8,8, 7, 13, 12, n 11 Faculty: 5, 10, 4, 13, 2, 3, 2,7,6, 6, 3, 4, n 12 Calculate the mean, median, and mode for each group. Do either of these distributions appear to be skewed?...
A population of N = 10 scores has a mean of μ = 24 with SS = 160, a variance of σ2 = 16, and a standard deviation of σ = 4. For this population, what is Σ(X − μ)? A. 0. B. 4. C. 16. D. 160
1. (2 points) For the following population N=5, calculate mean, standard deviation, and 7-scores for each score Scores: 8, 5, 4, 6,2
Consider the following raw scores, x: 2, 7,4,9, 1, 10. a. Assuming the scores represent a population, calculate the SS, the variance and the standard deviation of the scores. b. Assuming the scores represent a sample, calculate the SS, the variance and the standard deviation of the scores.
1. A student was asked to compute the mean and standard deviation for the following sample of n= 5 scores: 81, 87, 89, 86, and 87. To simplify the arithmetic, the student first subtracted 80 points from each score to obtain a new sample consisting of 1,7,9,6, and 7. The mean and standard deviation for the new sample are then calculated to be M=6 and s = 3. What are the values of the mean and standard deviation for the...
The sum of the squared deviation scores is SS = 60 for a sample of n = 5 scores. What is the variance for this sample?
1) Calculate the variance and standard deviation for each sample. (4 points) Note: you can use the Definitional Formulas (Slides #10 and 12) to compute sa and s, or you can choose the Computational Formulas (Slide #13). Either way is fine because the computational formula is just another form of the definitional formula, as discussed in the video. 2) In relation to the size of the mean values from two samples, what do the different standard deviations between the two...
