Question 1

An testable prediction about the relationship between two or more variables is called a

Accepted Answer

A hypothesis is a testable prediction about the relationship between two or more variables.

Question 2

The most important feature of a hypothesis is that it is

Accepted Answer

A hypothesis is a tentative explanation for a phenomenon. It is important that a hypothesis be capable of being disproven, because if it cannot be disproven, then it is not a scientific hypothesis.

Question 3

Jim believes that women are more patient than men. Which of the following is a hypothesis that might be used to test this belief?

Accepted Answer

A hypothesis that can be tested is a specific, measurable statement. "Women will wait in a theater ticket line longer than men will" is a testable hypothesis related to patience.

Question 4

Which of the following are potential sources of research hypotheses?

Accepted Answer

Research hypotheses can be derived from previous research, theoretical frameworks, and common sense or everyday observations.

Question 5

The text suggests that hypotheses can originate from all of the following sources EXCEPT:

Accepted Answer

Hypotheses are typically based on theory, previous research, or common sense, rather than random guessing, which lacks a systematic basis.

Question 6

Replicating previous research is a good idea because

Accepted Answer

Replicating previous research is important because science relies on skepticism, which involves questioning and verifying findings to ensure their reliability and validity.

Question 7

Replicating research that was done many years ago may increase

Accepted Answer

Replicating research increases external validity by confirming that the findings are consistent across different times, settings, and populations.

Question 8

Mary hypothesizes that socially popular high school students score lower on the SAT test than unpopular students. The biggest challenge to testing this hypothesis would be to obtain or develop an operational definition of

Accepted Answer

The biggest challenge would be to develop an operational definition of "social popularity," as it is a subjective and complex concept that can vary greatly among different individuals and contexts.

Question 9

Repeating a study, but controlling for factors that were not controlled in the original study may result in a study that has more ____ than the original.

Accepted Answer

Controlling for additional factors in a study typically increases its internal validity by reducing confounding variables and allowing for a clearer determination of causal relationships.

Question 10

Repeating a study, but using participants who differed from those in the original study (e.g., women instead of men) may result in a study that has more ____ than the original.

Accepted Answer

Using different participants can increase external validity by demonstrating that the findings are applicable to a broader population beyond the original study's sample.

Question 11

Repeating a study, but using the double-blind technique may result in a study that has more ____ than the original.

Accepted Answer

The answer of Repeating a study, but using the double-blind...

Question 12

Discovering a moderator variable challenges the ______ validity of the original finding.

Accepted Answer

A moderator variable affects the strength or direction of the relationship between independent and dependent variables, which challenges the external validity by suggesting that the original findings may not generalize across different conditions or populations.

Question 13

Which of the following might be a mediating variable?

Accepted Answer

Thoughts can mediate the relationship between independent and dependent variables.

Question 14

Which of the following might be a mediating variable?

Accepted Answer

The answer of Which of the following might be a...

Question 15

Which of the following might be a moderator variable?

Accepted Answer

A moderator variable is one that influences the strength or direction of the relationship between independent and dependent variables, and both types of situations and types of participants can serve as moderators in research studies.

Question 16

According to a null hypothesis

Accepted Answer

The null hypothesis states that there is no effect or no relationship between variables in a study, serving as a default or starting assumption for statistical testing.

Question 17

The null hypothesis can be

Accepted Answer

The null hypothesis can be disproven through statistical testing, but it cannot be proven true; we can only fail to reject it.

Question 18

A hypothesis must be

Accepted Answer

A hypothesis must be testable, meaning it can be supported or refuted through experimentation or observation.

Question 19

Which of the following studies can you do?

Accepted Answer

The answer of Which of the following studies can you...

Question 20

A rationale for a hypothesis can come from

Accepted Answer

A rationale for a hypothesis can be derived from common sense, previous research, and theory, as all these sources can provide a basis for formulating a hypothesis.
