Begin the fourth paragraph with these sentences: "Data were collected from a group of 20 adolescents (ages 14-18) who use cannabis daily to test the hypothesis using the correlational method. Each group completed three standardized psychological measures: (1) a short-term memory performance test, (2) a survey measuring their state of anxiety, and (3) a measure of their paranoia symptoms." State your predictions about the pattern of correlations among THC potency and the three measures if the hypothesis under investigation is correct. (7 pts) Figure 1 below presents a scatterplot of the variables THC and anxiety. What is a scatterplot? What does Figure 1 depict as the relationship between THC and anxiety in this study? (4 pts) . Use the formula to compute the correlation coefficient between THC and each of the three psychological measures. Also, compute the correlation coefficient between memory and anxiety (N.B. That's 4 correlation coefficients in total). For each coefficient, state the computed value of each of the four terms of the formula (i.e., r, I. II, and III). (6 pts) Begin the final paragraph with these sentences: "The results of the correlational method were valuable in addressing the hypothesis under study. However, several of the findings require future consideration." . Restate the hypothesis under study. Are the results of the correlational analysis consistent with the hypothesis? Why or why not? (4 pts) . Give an explanation for the relationship found in Figure 1. Give an explanation for the relationship found between memory and anxiety. (6 pts) . Describe a feature of the study that could be improved if you were to repeat it. (3 pts) Can correlational studies be used to evaluate hypotheses or should we only use experiments instead? Defend your answer. (4 pts) . Make a general conclusion from the results about the effects of substance use on the developing brain.
