If a group of high school biology students were given an anatomy exam developed for medical school students, it is likely that the _____ would be larger than the _____. mode; median mode; mean median; mean mean;median 10 1 2 3 4 5 6 7 8 9 10 11 12 13

4
**Which of the following is not affected by the actual magnitude of every value in the data set?**

Arithmetic mean Median Range Standard deviation 10 1 2 3 4 5

5
**If 400 test scores are distributed with a mean of 150 and s = 9, the variance of the test scores is:**

2.67 3 44.44 81 10 1 2 3 4 5

6
**A set of 10 scores has a mean of 50 and s = 8**

A set of 10 scores has a mean of 50 and s = 8. If you add 2 points to every score, the new standard deviation will be: 6 8 10 Cannot be determined 1 2 3 4 5

7
**A set of 10 scores has a mean of 50 and s = 8**

A set of 10 scores has a mean of 50 and s = 8. If you double each score, the new “s” will be: 4 8 16 64 10 1 2 3 4 5

**If there are 20 entries in an ordered list of data, the median will be the 10th entry.**

True False 10 1 2 3 4 5

10
**Which numerical summary is better for skewed data?**

5-number summary Mean, standard deviation Center, spread, shape 1.5*IQR 10 1 2 3 4 5

11
**“Arithmetic mean” is to “central tendency” as “standard deviation” is to _________.**

Average Variability Median Range 10 1 2 3 4 5

12
**Two classes took the same exam. Class M’s scores showed s = 6**

Two classes took the same exam. Class M’s scores showed s = 6.4 and class Q’s s = Which is true? Class M had a higher average Variance of class Q is 2 Class Q is more alike than class M Class M is 16 times more dispersed 10 1 2 3 4 5

13
**Given scores: 2, 6, 4, 3, 5. How far, on average, do the scores deviate from the mean?**

1.2 points 4.0 points 0 points 6.0 points 10 1 2 3 4 5
