2. For a population of N = 10 scores, you first measure the distance between each score and the
mean, then square each distance and find the sum of the squared distances. What value have you
calculated? a. SS b.the population variance c.the population standard deviation d.none of the
above 3. What are the values for SS and variance for the following sample of n = 3 scores?
Sample: 1, 4, 7 a.SS = 18 and variance = 6 b.SS = 18 and variance = 6 c.SS = 66 and variance
= 22 d.SS = 66 and variance 33 4. What is the variance for the following population of scores?
Scores: 5, 2, 5, 4 a.6 b.2 c.1.5 d.1.22 5.What term is used to identify the standard deviation
of the distribution of sample means? a.the expected value of M b.the standard error of M c.the
sample mean d.the central limit mean 6.A sample of n = 25 scores is selected from a
population with ? = 100 with ? = 20. On average, how much error would be expected between
the sample mean and the population mean? a.25 points b.20 points c.4 points d.0.8 points
Solution
2. b. the population variance 3. b. SS = 18 and variance = 6 4.b. 2 5. b. the standard
error of M c. 6. c. 4 points
