Question 1

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Unemployed but actively looking for job,3.Unemployed and quit looking for job?" are values from a

Accepted Answer

The values are options for a categorical variable, as they represent different categories of employment status.

Question 2

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "What do you think is the current unemployment rate?" result in

Accepted Answer

The unemployment rate is a ratio scale variable because it has a true zero point (0% unemployment) and the differences between values are meaningful.

Question 3

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How satisfied are you with the U.S.economy today with 1 = very satisfied,2 = moderately satisfied,3 = neutral,4 = moderately dissatisfied and 5 = very dissatisfied?" are values from a

Accepted Answer

The answer of SCENARIO 1-2
A Wall Street Journal poll asked...

Question 4

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How many more months do you think the U.S.economy will require to get out of a recession?" are values from a

Accepted Answer

The question asks for a specific number of months, which can only take on certain discrete numerical values. It is not a continuous numerical variable because it is not a range of values. It is not a categorical variable because it does not involve categories or labels. It is also not related to a table of random numbers, which is a tool used in statistics for random sampling.

Question 5

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How many out of every 10 U.S.voters do you think feel that the U.S.economy is in a good shape?" result in

Accepted Answer

The possible responses to the question represent a ratio scale variable because they have a true zero point (0 out of 10 voters) and can be compared using ratios (for example, twice as many voters think the economy is in good shape if 6 out of 10 voters agree compared to 3 out of 10).

Question 6

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the 2,150 adults make up

Accepted Answer

The 2,150 adults are a subset of the larger population of adults in the U.S., making them a sample.

Question 7

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "On the scale of 1 to 100 with 1 being extremely anxious and 100 being total not anxious,rate your level of anxiety in this U.S.economy" are values from a

Accepted Answer

The answer of SCENARIO 1-2
A Wall Street Journal poll asked...

Question 8

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "In which year do you think the last recession in the U.S.started?" result in

Accepted Answer

The responses to the question "In which year do you think the last recession in the U.S. started?" form an interval scale variable because the years are numeric and have equal intervals between them (one year). However, there is no true zero point because it is a subjective opinion rather than a measurable quantity. Therefore, it cannot be a ratio scale variable. It is also not an ordinal scale variable because the responses are not ordered in a meaningful way (e.g. from least to greatest or strongly disagree to strongly agree). Finally, it is not a nominal scale variable because the responses cannot be categorized into distinct non-numeric groups (e.g. male/female or yes/no).

Question 9

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How many people in your household are unemployed currently?" are values from a

Accepted Answer

The question "How many people in your household are unemployed currently?" asks for a specific number, meaning the possible responses are from a discrete numerical variable. A continuous numerical variable would have an infinite number of possible responses within a range, and a categorical variable would have responses that fall into defined categories or groups. A table of random numbers would not be relevant to this question.

Question 10

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How would you rate the condition of the U.S.economy with 1 = excellent,2 = good,3 = decent,4 = poor,5 = terrible?" result in

Accepted Answer

The responses represent an ordinal scale variable because they have a specific order or ranking (from excellent to terrible) but the numerical difference between each response is not necessarily equal. For example, the difference between "excellent" and "good" may not be the same as the difference between "decent" and "poor."

Question 11

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How satisfied are you with the U.S.economy today with 1 = very satisfied,2 = moderately satisfied,3 = neutral,4 = moderately dissatisfied and 5 = very dissatisfied?" result in

Accepted Answer

The possible responses represent a ranking or order based on levels of satisfaction, making it an ordinal scale variable. However, there is no meaningful zero point, so it cannot be considered as a ratio scale variable.

Question 12

The universe or "totality of items or things" under consideration is called

Accepted Answer

The universe or "totality of items or things" under consideration is called a population in statistics. Population refers to the entire group of individuals or objects that have one or more characteristics in common that the researcher is interested in studying.

Question 13

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How would you rate the condition of the U.S.economy with 1 = excellent,2 = good,3 = decent,4 = poor,5 = terrible?" are values from a

Accepted Answer

The responses are categories (excellent, good, decent, poor, terrible) represented by numbers, making it a categorical variable.

Question 14

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "What do you think is the current number of people unemployed in the country?" are values from a

Accepted Answer

The possible responses to the question "What do you think is the current number of people unemployed in the country?" are values from a discrete numerical variable, as the number of unemployed people can only take on a finite set of values (e.g. 5 million, 10 million, 15 million, etc.) and cannot take on fractional or continuous values.

Question 15

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How many people in your household are unemployed currently?" result in

Accepted Answer

The question asks for a specific quantity, which can be measured on a ratio scale. A ratio scale has a true zero point and allows for meaningful calculations such as ratios and percentages.

Question 16

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "How many out of every 10 U.S.voters do you think feel that the U.S.economy is in a good shape?" are values from a

Accepted Answer

The possible responses to the question "How many out of every 10 U.S. voters do you think feel that the U.S. economy is in good shape?" are values from a discrete numerical variable because the possible responses are whole numbers (e.g. 0, 1, 2, 3, ...). They are not continuous numerical values (e.g. 2.5, 3.2, 4.7, ...) and this question is not a categorical variable (e.g. yes/no, agree/disagree).

Question 17

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Unemployed but actively looking for job,3.Unemployed and quit looking for job?" result in

Accepted Answer

The question categorizes respondents into distinct groups without a specific order, making it a nominal scale variable.

Question 18

The portion of the universe that has been selected for analysis is called

Accepted Answer

The portion of the universe that has been selected for analysis is called a sample. It is a subset of the population or universe under study, from which observations and data are drawn to make inferences about the larger group. Therefore, option A is the correct answer. Option B is incorrect because a frame refers to a list of all the elements in the population. Option C and D are incorrect because primary and secondary data sources refer to the origin of the data, not the portion of the universe being studied.

Question 19

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "On the scale of 1 to 100 with 1 being extremely anxious and 100 being totally not anxious,rate your level of anxiety in this U.S.economy?" results in

Accepted Answer

The question asks respondents to rate their level of anxiety on a scale of 1 to 100, which creates equal intervals between each response choice. Therefore, this is an interval scale variable.

Question 20

SCENARIO 1-2
A Wall Street Journal poll asked 2,150 adults in the U.S.a series of questions to find out their view on the U.S.economy.
-Referring to Scenario 1-2,the possible responses to the question "In which year do you think the last recession in the U.S.started?" are values from a

Accepted Answer

The possible responses to the question about the year the last recession started are specific years (e.g., 2008, 2009), which are countable, distinct values, making them discrete numerical variables.
