Annabelle is a student at U of A. She is interested in the relationship between agreeableness and job performance for salespeople. She collects data and finds a statistically significant correlation between the two variables, r = -0.36, r2 = 0.13. Please explain her findings. Can you make a conclusion about the causal relationship between the two variables?

the correlation coefficient is found to be -0.36 which is moderate negative correlation between the agreeableness and the job performance for salespeople. This means that the slope is negative for the relationship between agreeableness and job performance for salespeople. Coefficient of determination is r2 = 0.13, which means that 13% variation can be explained by the regression line. We can conclude that the correlation coefficient of -0.36 means that there is negative change in value of job performance for salespeople whenever there is any change in agreeableness.
