Say Dr. Callahan measures her students' levels of narcissism. Her findings reveal that narcissism rates are higher in her male students versus her female students, a finding that is consistent with previous research. She also finds that the overall class average (11.5 out of 20) is lower than typical undergraduates' levels (15.5). Which of the following statements about this scenario is TRUE? She can conclude that being a SSU student is associated with lower levels of narcissism. O She needs to be skeptical of her findings because she did not have a random sample. She needs to be skeptical of her findings because she did not have random assignment. O She can conclude that her sample is externally valid because it replicates previous research. She can conclude that being a SSU student causes narcissism to decrease.
