Question 1: 52 points Wagner et. al., (1988) investigated the relationship between stress caused by daily life events and psychological symptomology in high-school seniors. Higher values reflect greater stress and more symptomology respectively. The table below contains data for 10 participants from their study. Daily Symptom Student Stress severity 30 ABCDEFGHI 30 99 27 94 9 80 20 70 3 100 15 109 5 62 10 81 J 24 37 74 121 a) Compute the Pearson product moment correlation coefficient for this data. Be sure to use the conceptual formulas presented in class. Be sure to interpret the correlation (12 marks).
