To determine

To identify:

whether the responses for question (i) nominal or ordinal.

Answer to Problem 49E

The responses for question (i) is ordinal.

Explanation of Solution

Given information:

A survey is administered by a marketing firm. Two of the people surveyed are Band J. Three of the questions are as follows:

i. Do you favor the construction of a new shopping mall?

(1) Strongly oppose (2) Somewhat oppose (3) Neutral (4) Somewhat favor (5) Strongly favor

ii. How many cars do you own?

iii. What is your marital status?

(1) Married (2) Single (3) Divorced (4) Domestically partnered (5) Other

Concept used:

There are various methods of collecting information by sampling. Once the information has been collected, the collection is called a data set. Variables can be divided into two types: qualitative and quantitative. Qualitative variables are also called categorical variable, classify individuals into categories. Quantitative variables are numerical and tell how much of something there is.

Qualitative variables come in two types: ordinal variables and nominal variables.

Ordinal variables are qualitative variables whose categories have a natural ordering.

Nominal variables are qualitative variables whose categories have no natural ordering.

Quantitative variables can be either discrete or continuous.

Discrete variables are those whose possible values can be listed. Often, discrete variables result from counting something, so the possible values of the variable are 0, 1, 2 and so forth.

Continuous variables can, in principle, take on any value within some interval.

The ordinal variables classify the values into categories, where, categories have a natural ordering. Therefore, the choices for response to given question, which has natural ordering with “strongly oppose”gives negative opinion and “strongly favor” stating positivedrawback. Therefore, the choices can be considered as logically ordered variable.

Therefore, responses to given question are ordinal.

To determine

To identify:

Whether J’s answer reflects more of something.

Answer to Problem 49E

J’s answer reflects that he is favor of constructing a new shopping mall unlike B.

ii. How many cars do you own?

iii. What is your marital status?

(1) Married (2) Single (3) Divorced (4) Domestically partnered (5) Other

On question (i), B answers (2) and J answers (4). J’s answer (4) is greater than B’s answer (2).

It is given that B answered 2 that is “Somewhat oppose” and J answered 4 that is “Somewhat favor”. Thus J’s answer reflects more of positivity than B’s answer, though it is not giving the sure intensity in favor of the construction.

To determine

To identify:

Whether J’s answer reflects twice as much of something.

Answer to Problem 49E

The variable response to given question is categorical in nature, so it doesn’t not imply J’s answer to given question is twice favorable as much of something.

It is given that B answered 2 that is “Somewhat oppose” and J answered 4 that is “Somewhat favor”.Thus J’s answer reflects more of positivity than B’s answer, though it is not giving the sure intensity in favor of the construction.It is given J’s answer to given question is twice as large as B, which does not implies twice as much of something, because, the variable response to given question is categorical in nature that is qualitative not quantitative.

Whether question (ii) qualitative or quantitative.

Answer to Problem 49E

The responses for question (ii) isquantitative.

A statistical factor classifies people into classes, and it indicates how much or how much of something there is. The variable number of cars owned by one tells the number of cars one can be possessed.

Therefore, responses to given question is quantitative in nature.

To determine

To identify:

Whether B’s answer reflect more of something and does it reflect B’s answer is twice as much as something.

Answer to Problem 49E

The response is quantitative, B’s answer reflect that she has more cars than J.

Yes! B’s answer reflects that she has twice as many cars as what J have.

It is given that in response to given question, B answered 2 and J answered 1.

The above result clearly tells that B owns more cars than J. B’s answer reflect twice as much as cars than J.

Whether the responses to question (iii) nominal or ordinal.

Answer to Problem 49E

The responses to question (iii) is nominal.

A nominal variable classifies the values into classes, but there is no natural ordering in the categories, whereas the ordinal variables classify the values into categories where categories have natural ordering. Therefore, the responses to given question classifies one’s marital status into five categories.

Therefore, responses to given question are nominal.

To determine

To identify:

Whether B’s answers reflect more of something and reflect twice as much as something.

Answer to Problem 49E

B’s response of 4 and J’s response of 2 do not reflect more of something. B’s answer does not reflect twice as much as J’s.

Continuous variables can, in principle, take on any value within some interval.

A nominal variable classifies the values into classes, but there is no natural ordering for the categories, whereas the ordinal variables classify the values into categories where categories have natural ordering. Therefore, the responses to given question classifies one’s marital status into five categories.

Response to Marital status are nominal in nature, thus primarily the variable marital status is categorical. Hence, B’s response of 4 and J’s response of 2 do not reflect more of something. Thus, B’s answer does not reflect twice as much as J’s.
