I. Multiple Choice. Encircle the letter of the correct answer (2pts each)
1. Six friends in a mathematics class received test grades of 90, 80, 75, 76,
95 and 85. What is the mean or average grade of the six students?
а. 83
c. 84.5
b. 83.5
d. 84
2. The data are as follows: 18, 15, 21, 15, 16, 14 and 20. What is the
median of this data?
b. 16
d. 14
a. 15
c. 21
3. The data are as follows: 1, 12, 11, 5, 16, 4 and 1. What is the mode of
this data?
а. 11
b. 12
с. 1
d. none
4. Five friends in a statistics class received test grades of 92, 81, 76, 75 and
65. What is the range of this data?
а. 17
b. 27
c. 25
d. 37
5. When would there be an advantage to using the median instead of the
mean when computing the measure of central tendency of a particular
data set?
a. When the data set is open-ended.
b. When the data set has an extremely high data value.
c. When you must determine whether a data value falls into the
upper or lower half of the distribution.
d. All of the above.
II. True or False. Write True if the statement is correct and False if otherwise.
(2pts each)
1. AUØ = 0.
2. The empty set is considered subset of all sets.
3. U'- 0.
4. A set with n elements can have 2" total number of distinct subsets.
5. Xn U= X.
III. Perform as Instructed.
1. Choose 9 two-digits numbers of your own choice and calculate the mean,
median and mode. (15 pts)
2. Illustrate the relationship of set U, X, Y and Z in Venn diagram. (15 pts)
Let U= {m, a, t, h, w, i, z, r, d, 1, 2, 3, 4, 5, 6, 7, 8, 9,
X= {w, i, z, a, r, d, 3},
Y- (m, a, t, h, 3, 6, 9),
Z - (a, i, m, 1, 2, 3).

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
