Questions with 100% Correct Answers
Six children have collected these amounts in their piggy banks: $10, $33, $45,
$23, $1, and $68. What is the median of their savings?
a. $28
b. $33
c. $23
d. $66 Correct Answer: answer: a. $28
Rearrange the numbers in increasing order: 1, 10, 23, 33, 45, and 68. The median
of a sequence of numbers is the middle value. Since there are six numbers,
there are two values in the middle 23 and 33 and, therefore, the median is the
average of these values. The median is 28.
What do you call questions that have more than one possible answer, and

c. non-statistical questions
b. rhetorical questions Correct Answer: answer: b. statistical questions
A non-statistical question just has one answer that does not change. A rhetorical
question does not require to be answered. Probing questions require
elaboration of the topic.
The weights of twenty trouts were recorded: 12, 13, 13, 14, 14, 14, 14, 15, 15, 15,
16, 16, 16, 17, 17, 17, 17, 17, 18, and 34. If the weight of the heaviest trout is
removed from the data, which statistical parameter will drastically change?
a. range
b. median
c. mean
d. mode Correct Answer: answer: a. range
Since the mean, median, and mode are measures of center, outliers will not
have much effect. The range will be greatly affected since it measures the
difference between the highest and lowest.

a. quadrant
b. coordinate
c. abscissa
d. origin Correct Answer: answer: d. origin
Abscissa refers to the x-axis, while ordinate refers to the y-axis. Quadrant refers to
the four sections in the Cartesian plane that are divided by the two axes.
What shape is obtained by drawing the polygon whose vertices are the points
of coordinates (2,0), (0,2), (-2,0), and (0,-2)?
a. square
b. rectangle
c. parallelogram
d. trapezoid Correct Answer: answer: a. square
