Question

question 5 (2 points)
in an experimental study, external validity refers to the
○ extent to which the results of the study can improve human life.
○ fact that the study was subjected to some form of experimenter bias.
○ fact that the finding of the study is replicated each time the experiment is conducted.
○ extent to which the experimental design reflects the real - world issues it explores.

question 6 (2 points)
in correlational research, the \third variable problem\ refers to a circumstance in which
○ scatter plots for positive, negative, and zero correlations are the same.
○ the correlation between variables equals causation.
○ a variable that has not been measured accounts for the relationship between two other variables.
○ experimenter bias increases the effects of research participant bias.

Explanation:

For Question 5, external validity in experimental studies is about how well the results generalize to real - world situations. It's not about improving human life, experimenter bias, or replication (which is related to reliability). For Question 6, in correlational research, the third - variable problem occurs when an unmeasured variable influences the relationship between two measured variables. It's not about scatter plots being the same, correlation equaling causation, or biases interacting.

Answer:

Question 5: The extent to which the experimental design reflects the real - world issues it explores.
Question 6: A variable that has not been measured accounts for the relationship between two other variables.
