Question

question 10 1 pts in the context of experimental research, internal validity refers to the: extent to which the experimental design reflects the real-world issues it explores. extent to which changes in the dependent variable are genuinely due to the manipulation of the independent variable. degree to which the results of the experiment are generalizable to the larger population. methodology used to carry out the random assignment of samples.

Explanation:

To determine the correct answer, we analyze each option:

• The first option describes external validity (relating to real - world reflection).
• The second option: Internal validity in experimental research is about whether the changes in the dependent variable are truly caused by the manipulation of the independent variable (controlling for confounding variables).
• The third option is about external validity (generalizability to the population).
• The fourth option is about random assignment methodology, not internal validity.

Answer:

B. extent to which changes in the dependent variable are genuinely due to the manipulation of the independent variable.
