Question 1

EXPLANATION: The rating is ordinal scale not an interval scale because the difference in rating
between "excellent" and "good" does not have to be the same as the difference between "poor" and
"terrible".
KEYWORDS: ordinal scale, types of data
-Referring to Scenario 1-1, the possible responses to the question "Out of a 100 point score with
100 being the highest and 0 being the lowest, what is your satisfaction level with the Blu-ray
Player that you purchased?" result in
A) a nominal scale variable.
B) an ordinal scale variable.
C) an interval scale variable.
D) a ratio scale variable.

Accepted Answer

The satisfaction level out of a 100-point score is an interval scale because it has equal intervals between points and no true zero point.

Question 2

True or False: The answer to the question "How do you rate the quality of your business statistics
course" is an example of an ordinal scaled variable.

Accepted Answer

An ordinal scaled variable represents categories with a meaningful order, such as ratings (e.g., poor, fair, good, excellent) where the order matters but the intervals between values are not equal.

Question 3

EXPLANATION: The rating is ordinal scale not an interval scale because the difference in rating
between "excellent" and "good" does not have to be the same as the difference between "poor" and
"terrible".
KEYWORDS: ordinal scale, types of data
-Referring to Scenario 1-1, the possible responses to the question "What brand of Blu-ray player
Did you purchase?" result in
A) a nominal scale variable.
B) an ordinal scale variable.
C) an interval scale variable.
D) a ratio scale variable.

Accepted Answer

The question "What brand of Blu-ray player did you purchase?" results in a nominal scale variable because it categorizes the data without any order or ranking.

Question 4

An insurance company evaluates many numerical variables about a person before deciding on an
appropriate rate for automobile insurance.The distance a person drives in a year is an example of
a _______ variable.

Accepted Answer

The answer of An insurance company evaluates many numerical variables...

Question 5

appropriate rate for automobile insurance.The number of tickets a person has received in the last
3 years is an example of a _______ numerical variable.

Accepted Answer

The answer of An insurance company evaluates many numerical variables...

Question 6

SCENARIO 1-1
The manager of the customer service division of a major consumer electronics company is interested
in determining whether the customers who have purchased a Blu-ray player made by the company
over the past 12 months are satisfied with their products.
-Referring to Scenario 1-1, the possible responses to the question "How many people are there in
Your household?" result in
A) a nominal scale variable.
B) an ordinal scale variable.
C) an interval scale variable.
D) a ratio scale variable.

Accepted Answer

The number of people in a household is a ratio scale variable because it has a true zero point and the differences between values are meaningful.

Question 7

SCENARIO 1-1
The manager of the customer service division of a major consumer electronics company is interested
in determining whether the customers who have purchased a Blu-ray player made by the company
over the past 12 months are satisfied with their products.
-Referring to Scenario 1-1, the possible responses to the question "How would you rate the quality
Of your purchase experience with 1 = excellent, 2 = good, 3 = decent, 4 = poor, 5 = terrible?"
Result in
A) a nominal scale variable.
B) an ordinal scale variable.
C) an interval scale variable.
D) a ratio scale variable.

Accepted Answer

The responses are on an ordinal scale because they represent a ranked order of satisfaction levels.

Question 8

True or False: A continuous variable may take on any value within its relevant range even though
the measurement device may not be precise enough to record it.

Accepted Answer

A continuous variable can theoretically take any value within a range, but practical measurement limitations may prevent capturing every possible value.

Question 9

True or False: The answer to the question "What is your sleeping bag temperature rating?" is an
example of a ratio scaled variable.

Accepted Answer

The answer to the question "What is your sleeping bag temperature rating?" is an example of an interval scaled variable.

Question 10

True or False: Student grades (A to F)are an example of continuous numerical data.

Accepted Answer

Student grades (A to F) are categorical data, not continuous numerical data, as they represent distinct categories rather than a range of numerical values.

Question 11

True or False: The possible responses to the question "How many times in the past three months
have you visited a city park?" are values from a discrete variable.

Accepted Answer

The number of times someone visits a city park is countable and can only take on whole number values, making it a discrete variable.

Question 12

True or False: The amount of coffee consumed by an individual in a day is an example of a
discrete numerical variable.

Accepted Answer

The answer of True or False: The amount of coffee...

Question 13

An insurance company evaluates many numerical variables about a person before deciding on an
appropriate rate for automobile insurance.A person's age is an example of a _______ numerical
variable.

Accepted Answer

The answer of An insurance company evaluates many numerical variables...

Question 14

True or False: The answer to the question "How many hours on average do you spend watching
TV every week?" is an example of a ratio scaled variable.

Accepted Answer

A ratio scale has a true zero point and equal intervals, which applies to hours spent watching TV as it can be measured from zero upwards with meaningful comparisons.

Question 15

True or False: The answer to the question "What is your favorite color?" is an example of an
ordinal scaled variable.

Accepted Answer

Ordinal scaled variables have a meaningful order or ranking, but "favorite color" is a nominal variable with no inherent order.

Question 16

True or False: The possible responses to the question "How long have you been living at your
current residence?" are values from a continuous variable.

Accepted Answer

The answer of True or False: The possible responses to...

Question 17

An insurance company evaluates many numerical variables about a person before deciding on an
appropriate rate for automobile insurance.The number of claims a person has made in the last 3
years is an example of a _______ numerical variable.

Accepted Answer

The answer of An insurance company evaluates many numerical variables...

Question 18

An insurance company evaluates many numerical variables about a person before deciding on an
appropriate rate for automobile insurance.How long a person has been a licensed driver is an
example of a _______ numerical variable.

Accepted Answer

The answer of An insurance company evaluates many numerical variables...

Question 19

True or False: Faculty rank (professor to lecturer)is an example of discrete numerical data.

Accepted Answer

Faculty rank is an example of categorical data, not numerical, as it represents distinct categories or labels without inherent numerical value.

Question 20

EXPLANATION: The rating is interval scale not ordinal scale because the difference in rating
between "80" and "90" can be treated as the same as the difference between "30" and "40" but a
rating of "80" does not imply twice the level of satisfaction level as a rating of "40".
KEYWORDS: interval scale, types of data
