A higher coefficient rating means the two variables have a stronger relationship, with the value of one indicating that the variables grow at a one-to-one rate.To find the correlation coefficient between age and max bench press, we can take the square root of R2: Correlation coefficient = √R2 = √0.4773 = 0.6909. Since the sign is negative for age in the regression equation, this correlation coefficient is negative. Thus, the correlation coefficient between age and max bench press is -0.6909.Because the correlation coefficient is greater than the critical value (0.970 > 0.888), it is reasonable to conclude that the finishing times of Barbies Bomber in the 5/16-mile race are approximately normally distributed.

Spearman's correlation coefficient = covariance (rank (X), rank (Y)) / (stdv (rank (X)) * stdv (rank (Y))) A linear relationship between the variables is not assumed, although a monotonic relationship is assumed. This is a mathematical name for an increasing or decreasing relationship between the two variables.

1. As a rule of thumb, a correlation coefficient between 0.25 and 0.5 is considered to be a "weak" correlation between two variables. 2. This rule of thumb can vary from field to field. For example, a much lower correlation could be considered weak in a medical field compared to a technology field. Be sure to use subject matter expertise ...A correlation measurement between two variables must satisfy the following points: 1. It takes values between -1 and \( { +1 } \). 2. There is a positive correlation between X and Y if the value of the correlation coefficient is positive; a perfect positive correlation corresponds to a value of \( { +1 } \). 3.Correlation Coefficient Practice - TI-84 Name _____ HighSchoolMathTeachers©2020 Page 1 1 A study compared the number of years of education a person received and that person's average yearly salary.
