Question 1

Uncertainty is related to sticky theory in that&#10;A) reality is unpredictable and answers to many important questions are not clear.&#10;B) sticky theory is the opposite of recognition of uncertainty.&#10;C) both a and b&#10;D) neither a nor b

Accepted Answer

B

Question 2

What are some criteria to evaluate sources of information?&#10;A) Sources are free of vested interests in trying to convince you of something.&#10;B) Sources have knowledge of the subject.&#10;C) Standards of evidence can be applied to the content.&#10;D) all of these (a, b, c)

Accepted Answer

All three criteria (a, b, c) are important in evaluating sources of information. It is important to choose sources that are free of biases or vested interests, have knowledge of the subject matter, and can be held to standards of evidence.

Question 3

What are the main strong point(s) of the Consumer Reports (CR) data on car reliability?&#10;A) The sample is very large and updated each year.&#10;B) The questionnaire is fairly comprehensive, asking questions about many components of auto reliability.&#10;C) CR accepts commercial advertising.&#10;D) only a and b

Accepted Answer

The main strong points of CR data on car reliability are that the sample is very large and updated each year and the questionnaire is fairly comprehensive, asking questions about many components of auto reliability. CR does not accept commercial advertising, so choice C is incorrect. Therefore, the correct answer is only a and b.

Question 4

Suppose A is religiosity and B is happiness. Can one conduct a randomized experiment to find out whether A affects B?&#10;A) Yes, assign individuals to one of the major religions and later ask how happy they are.&#10;B) Yes, assign individuals to a level of happiness and later ask them what their religious preference is.&#10;C) No random assignment can be made.&#10;D) none of these (a, b, c)

Accepted Answer

Random assignment cannot be made in this scenario as religiosity is not randomly assigned to individuals. It is a personal choice and cannot be manipulated by the researcher. Therefore, any correlation found between religiosity and happiness could potentially be due to other factors that were not controlled for in the study.

Question 5

Consider the Consumer Reports auto reliability data as a relationship between two variables: (a) make of automobile, and (b) frequency of repairs.&#10;A) The independent variable is frequency of repairs.&#10;B) The independent variable is make of automobile.&#10;C) The independent variable is the Consumer Reports data.&#10;D) none of these (a, b, c)

Accepted Answer

In this scenario, the make of automobile is being used as the independent variable to predict or explain the frequency of repairs. Therefore, the correct answer is B, as the independent variable is the make of automobile. A is incorrect because frequency of repairs is the dependent variable being explained or predicted by the make of automobile. C and D are also not correct as the Consumer Reports data is not an independent variable in this relationship.

Question 6

Consider the Consumer Reports auto reliability data as a relationship between two variables: (a) make of automobile, and (b) frequency of repairs.&#10;A) The dependent variable is frequency of repairs.&#10;B) The dependent variable is make of automobile.&#10;C) The dependent variable is the Consumer Reports data.&#10;D) none of these (a, b, c)

Accepted Answer

The dependent variable is the variable that is being measured or observed in response to the independent variable. In this case, the independent variable is the make of automobile and the dependent variable is the frequency of repairs. The frequency of repairs is what is being measured or observed in response to the make of automobile. Therefore, choice A is the correct answer.
