Most of you have heard the saying, “Just because two things are related doesnât mean there is a cause-and-effect relationship.” More simply, two things can be related to each other but not have a relationship where one is causing the other to occur. Using the telephone on a daily basis and having high blood pressure may be statistically related, but it might be unreasonable to conclude that having high blood pressure causes you to use the telephone or vice versa. Such is the world of correlational research design.
This week focuses on correlational research designs and their applicability to quantitative research in forensic psychology. From the use of a Pearson correlation coefficient to using the chi-square statistic, correlational research designs help you to â knowâ if two seemingly related variables truly are related.
By the end of this week, you should be able to:
Apply concepts of positive and negative linear and curvilinear relationships
Analyze strengths and limitations of correlational designs in forensic psychology research
Sample Solution
The independence and decentralization of the military allowed it to act largely on its own will as characterized in the Manchurian incident in 1931 and the Marco Polo bridge explosion in Shanghai. Because these incidents went unpunished and the Japanese public rallied around them the military was able to push for greater militarism and an increasingly active role in government till the entire government was run by the military. The London Treaty and Japanâs rejection by large European powers at the Versailles conference angered many in the military who felt that Japan was being denied its place at the table with the great powers. This lead to a disenfranchisement with the parliamentary government who the military felt had capitulated to the western powers in treaties and by stopping its colonial expansion during the nineteen twenties. Once Japan commenced on the path of militarism it found that because of its technological edge it could defeat other Asian powers this increased Japanâs sense of superiority and feed the fires of nationalism. These fires grew as following the 1931 Manchurian incident Japan invaded Manchuria then most China. In South East Asia Japan quickly expanded breaking up British, Portuguese, and Dutch colonialism. Japanese militarism occurred not by an organized plan but rather through passive acceptance by the Japanese public. A compliant Japanese public coupled with a independent army were two factors that pushed Japan toward militarism in the 1930âs.>
