1. correlation iNZight gives r

2. POSITIVE linear correlation r=1 "Perfect" 0.9<r<1 "Strong" 0.7<r<0.9 "Significant" 0.5<r<0.7 “Moderate“ 0.3<r<0.5 "Weak” 0<r<0.3 "Not significant”

3. NEGATIVE linear correlation r=-1 "Perfect" -0.9<r<-1 "Strong" -0.7<r<-0.9 "Significant" -0.5<r<-0.7 “Moderate“ -0.3<r<-0.5 "Weak” 0<r<-0.3 "Not significant”
