However, the definition of a strong correlation can vary from one field to the next. 0.0 c. +0.6 d. +1.0 e. -1.0, A linear regression analysis produces the equation y = 5.32 + (-0.846)x. Explain how the two correlations differ. Choose all that apply. 0 votes. a. Which correlation coefficient should we use if we want to find out whether a relationship exists between two variables that are both interval or ratio variables? a. Answer: -0.85 (Option d) is the strongest correlation coefficient which represents the strongest correlation as compared to others. Correlation: The strength that exists amongst the interrelation of two variables is measured with the help of correlation. -1A + 2B \leq 70 b. Which of the following is the weakest correlation?

For the relationships that are unacceptable for linear programs, state why. There appears to be a positive linear relationship between the two variables. A correlation measures and describes the linear relationship between two variables. Multivariate analysis is appropriate to examine complex human behavior and demographic characteristics .However, multiple covariates with high correlation may complicate interpretation of a regression analysis .For example, having a highly correlated variable in a model can result in significant coefficient changes of other variables. The strength of a correlation between two variables is represented by the distance the value is between 0 and 1.0. Hope this helps!
