Math Problem Statement
Correlation coefficient is the strength of the linear relationship between two quantitive variables. Sort the coefficients from strong to weak and make sure to put them from least to greatest in each column. Columns are strong correlation, moderate correlation and weak to no correlation. -0.45,1,-1,0.15,-0.85,0.63,0.52,0,-0.75
