You are a professor interested in studying the relationship between social media and mental health. You immerse yourself in the literature and read dozens of research articles. After reading the articles it was evident the field claims adolescents with more than 100 social media interactions (post, likes, comments, reactions) will have anxiety. You want to test this claim and decided to carry out a research study. Before you go out to recruit adolescents at a middle school you need to choose an instrument to use in your study that assess anxiety levels. You found two instruments after searching the internet. One instrument, called Form A, cost money to use it and is the gold standard in assessing anxiety levels in adolescent. The other instrument is a free instrument developed by a professor called Form B. You don't want to spend a lot of money buying Form A. If Form A positively correlated with Form B you can justify using Form B in your study. You get a random sample of 10 adolescents and give them Form A (yes you purchased only a few to test) and Form B (yes, you contacted the professor and asked for his permission to use his inventory). Both inventories are scored on an interval scale (continuous variables). Student 1 2 3 4 5 6 20. What correlation coefficient would you calculate to see if you could use Form B? Why? 7 8 Form A 5 8 6 7 8 955 8 Form B 6 7 8 4 7 w 00 00 8 8 3 I
