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

Question 3

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 "What brand of Blu-ray player did you purchase?" result in

Accepted Answer

The possible responses to the question "What brand of Blu-ray player did you purchase?" are categories or names of brands, which represents a nominal scale variable.

Question 4

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

Accepted Answer

The question "How many people are there in your household?" results in a ratio scale variable because it involves a countable number of people, which has a true zero point (indicating no people in the household) and allows for meaningful comparisons between responses.

Question 5

Faculty rank (professor to lecturer)is an example of discrete numerical data.

Accepted Answer

Faculty rank (professor to lecturer) is an example of ordinal data because it represents categories with a meaningful order but without a precise mathematical difference between them.

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 would you rate the quality of your purchase experience with 1 = excellent,2 = good,3 = decent,4 = poor,5 = terrible?" result in

Accepted Answer

The possible responses to the question are ranked in a specific order from most positive (excellent) to most negative (terrible), resulting in an ordinal scale variable.

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 "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 results in:

Accepted Answer

The response to the question represents an interval scale variable because it has equal intervals between scores and the difference between scores is meaningful. However, there is no clear zero point or absolute reference point for satisfaction, so it cannot be considered a ratio scale variable. It is not a nominal scale variable because the responses cannot be categorized into distinct categories, and it is not an ordinal scale variable because the responses cannot be ranked or ordered.

Question 8

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

Visiting a city park is a countable action that can only take on whole number values, making it a discrete variable. Therefore, its possible responses are values from a discrete variable.

Question 9

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

This is true. For example, a scale may only be able to display weight values in increments of 0.5 pounds, but a person's weight could be any value within a range of pounds.

Question 10

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 11

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 "What is your age at last birthday ?" results in:

Accepted Answer

Age is a ratio scale variable because it has a meaningful zero point (birth), and the differences between values are meaningful, allowing for a full range of mathematical operations (addition, subtraction, multiplication, division).

Question 12

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 duration of time someone has lived at their current residence can be measured in a continuous scale, such as years, months, days, or even smaller units of time, allowing for an infinite number of possible values.

Question 13

Student grades (A to F)are an example of continuous numerical data.

Accepted Answer

Student grades are not continuous numerical data, as they are not measured on a continuous scale. They are categorical data, with a set of discrete categories (A, B, C, D, F).

Question 14

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

Accepted Answer

A discrete numerical variable can only take on specific values, typically integers, and cannot be divided into smaller units. The amount of coffee consumed in a day can be measured in fractional units, making it a continuous numerical variable, not a discrete one.

Question 15

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

Accepted Answer

The answer of The answer to the question "What is...

Question 16

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 scaled variable is one that has a true zero point and allows for comparisons of absolute magnitudes. The number of hours spent watching TV can be measured from an absolute zero (no hours watched) and compared in terms of how many times more one value is than another, fitting the criteria of a ratio scale.

Question 17

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

The response to the question can be ranked or ordered, making it an ordinal scaled variable.

Question 18

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

Accepted Answer

The question "What is your favorite color?" is an example of a nominal scaled variable because it is a categorical variable with no inherent order or ranking.

Question 19

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 20

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...
