All of the questions on it can be answered accurately by the subject
It measures what it is supposed to measure
It produces the same result no matter which version of the test is used

Case study
Survey
Question 5

Using animal subjects
Random assignment
Single-blind procedure
Question 6
When doing research involving deception with human subjects, researchers have an obligation to do which of the following?
Question 6 options:
Tell subjects the truth about the study’s purpose and methods after the study is completed
Let subjects withdraw from the study at any time if they don’t want to keep participating
Prevent mental and physical harm to subjects
All of the above
Question 7
Good scientific research must have precise hypotheses, replicability, falsifiable theories and hypotheses, and parsimonious explanations.
Question 7 options:
True
False
Question 8
Self-report data can be misleading, and therefore not reliable in research. Why?
Question 8 options:
All of the above
People may not always understand the questions asked
People may sometimes give answers based on wishful thinking
People sometimes intentionally lie
Question 9
We can always draw cause-and-effect conclusions about correlative data.
Question 9 options:
True
False
Question 10
If a result is statistically significant, it is probably not due to chance.
Question 10 options:
True
False
Question 11
Researchers use inferential statistics to determine the likelihood that a result is due simply to chance.
Question 11 options:
True
False

Question 12 options:
True

Question 13 options:
True
False

Content validity is a test’s ability to measure all the important aspects of the characteristic being measured.
Question 14 options:
True
False

Experimenter bias occurs when researchers’ preferences or expectations influence the outcome of their research.
Question 15 options:
True
False
Question 16
How can we determine if a test has good validity?
Question 16 options:
It produces the same result no matter which version of the test is used
It produces the same result when it is given at different times to the same group of people
All of the questions on it can be answered accurately by the subject
It measures what it is supposed to measure
