The t-test value calculated showed a significant difference in the expected direction, validating the research hypothesis. [ t (675) = 19.25; p < 0.001, one tailed]. The effect size examined with the squared point-biserial correlation showed that a reasonable amount of variation was attributed to the factor.
Psychological research, regardless of the specific topic of study, is based upon the same scientific principles as the other “hard” sciences like physics and chemistry. Nevertheless, psychology has a long history of fighting a commonly held perception that it does not qualify as a scientific discipline and that it generates knowledge that is mere common sense. In many cases, however, common sense leads to an incorrect appreciation of phenomena that have been scientifically investigated by psychologists. Several studies have shown that undergraduate students and lay people alike hold many misconceptions about psychology. These misconceptions have been demonstrated in the United States and England and in several different courses of study.
McCutcheon, Furnham, and Davis (1993) asked if there was a significant difference in the prevalence of misconceptions about psychology between American and English university students. They administered a 65 item multiple-choice questionnaire and found that English students generally did better than American students, though neither group answered more than half of the question correctly. While the authors offered no clear explanation for either the poor performance or the difference between the two groups, they speculated that selective reporting in the mass media may contribute to both the formation of misconceptions and their resolution.
Martin, Sadler, and Baluch (1997) tested undergraduate students from psychology, sociology, business, English and engineering from Middlesex University, U.K. on their general
