6. The correct answer is Option D. The most serious problem with case studies is that their findings cannot be applied to psychology in general.
7. The correct answer is Option C. Statistical significance is the probability that research results are due to chance whereas effect size is the statistic that estimates the magnitude of researcher results.
8. The correct answer is Option D. Statistics cannot be mutated or laundered.
9. The correct answer is Option B. This relationship is an example of negative correlation.
10. The correct answer is Option D. This represents the third variable problem or the illusory correlation.
