12 A researcher is interested in the relationship between happiness and GPA of high school students. After surveying 50 students, he determines that there is a correlation between these two variables of 90. This is considered a : a) strong negative linear correlation b) strong positive linear correlation c) weak negative linear correlation d) weak positive linear correlation Question 13 The variables K and Q are related such that when K increases, Q increases at first and then decreases such that the data roughly follow rainbow shape. The relationship between K and Q can be best described as: a) curvilinear b) Linear c) inverse A researcher is interested in the relationship between happiness and GPA of high school students. After surveying 50 students, he determines that there is a correlation between these two variables of 90. This is a: 1-a strong negative linear correlation 2- strong positive linear correlation 3- weak negative linear correlation 4- weak positive linear correlation
