Comprehensive Final Exam
COMPREHENSIVE FINAL EXAM
Student: Dallas Ventre
*all answers are typed in red*
The Comprehensive Final Exam covers all Reading & Study material for the course. The exam is open-book/open-notes and contains 50
questions requiring calculations and interpretations of data and test/assessment material that teachers would likely encounter in the
classroom. The exam has no time limit and is to be submitted as a Microsoft Word document through the appropriate submission link. Fill
in the blanks as appropriate; for multiple-choice questions, identify your response by circling, underlining, highlighting, or marking with
an asterisk.
I. Frequency Distributions
The following are 50 scores from a history examination.
37 39 42 30 38 20 17 16 15 6
25 22 15 25 31 18 21 13 5 11
27 26 26 22 31 15 16 22 17 6
22 27 27 32 17 32 14 12 23 18
28 29 33 28 19 19 34 20 21 29
From these scores, construct a frequency distribution table. Use nine classes, with the first
class 0 4 and the last 40 44.
Class Interval Tally Frequency

6. 15 19 IIIIIIIIIIII 12
7. 10 14 IIII 4
8. 5 9 III 3
9. 0 4 0
II. From the following scores on two tests, calculate the values indicated:
, Comprehensive Final Exam
Test 1 (X): 29, 28, 25, 25, 22, 22, 21, 20, 19, 19
Test 2 (Y): 34, 31, 35, 30, 31, 28, 28, 25, 24, 24
10. Mean of Test 1 (X)
Mx= 23
11. Mean of Test 2 (Y)
My= 29
12. Summation of squared deviations scores for Test 1 Σx2= 5406
13. Summation of squared deviations scores for Test 2 Σy2 = 8458
14. Summation of the product of deviation scores for Test 1 and Test 2 Σxy = 6777
15. Correlation Coefficient: r =
0.8457
III. Twenty students received the following scores on a short quiz:
23, 20, 20, 19, 19, 19, 18, 18, 18, 18, 18, 17, 17, 17, 15, 14, 13, 13, 12, 12.
Calculate the following:
16. Mean= 17
17. Median= 18
18. Mode= 18
19. SD = 2.95581
20. If this small sample is normally distributed, 68% of the scores should fall between what two values? 14 and
20
IV. A student takes examinations in a history course and an English course. The following information is taken from the two
tests:
