1. Write a brief introduction that includes a hypothesis statement, statistical description of results, and your conclusion of the results for the Correlation of Aggressive and Rule-Breaking Behavior from Teachers' Ratings study that was presented in class.

In the Correlation of Aggressive and Rule-Breaking Behavior from Teachers' Ratings study, the researcher, Tom has the hypothesis that the teachers' rating of students' who are purported to have high levels of maladaptive behavior will show a statistically significant correlation between Rule Breaking and Aggressive Behavior. Statistically, the correlation is r=.71 which indicates that there is a strong relationship between the two ratings so as aggression ratings go up, so do the rule breaking ratings. The reason why this is is because a correlation of r=.71 indicates a large effect size and that the relationship has a positive meaning (When one increases the other increases as well).

2. Write a brief introduction that includes a hypothesis statement, statistical description of results, and your conclusion of the results for the Externalizing Problem Behavior and later Academic Underachievement study that was presented in class.

In the Externalizing Problem Behavior and later Academic Underachievement study, the researcher Tom is examining teachers' ratings of students' Depression, Oppositional Defiant, and ADHD behaviors at the beginning of the year with end of the year Word Reading skills. Statistically, the experiment is statistically significant, the overall effect size is .03, and not all of the predictors significantly measure up to .05. Therefore all the predictors significantly predict end of the year word reading skill.
