CHAPTER 1: THINKING CRITICALLY WITH PSYCHOLOGICAL SCIENCE chapter 1 Indicate the answer choice that best completes the statement or answers the question. If results are statistically significant but have a small effect size, the results may lack practical significance. lack a cause-effect relationship. represent a negative relationship. represent a neutral relationship. In one study, introductory psychology students were fitted with electronically activated recorders so that researchers could sample their daily activities. The researchers were employing a scientific method known as naturalistic observation. the double-blind procedure. experimentation. the case study.

Seven members of a boys' club reported the following individual earnings from their sale of cookies: $2, $9, $8, $10, $4, $9, and $7. In this distribution of individual earnings the median is greater than the mean and greater than the mode. the median is less than the mean and less than the mode. the median is greater than the mean and less than the mode. the median is less than the mean and greater than the mode.
