The value of the correlation coefficient (r) associated with victors function was -0.91, the value or r for Vladimir’s function was 0.73, the value of r for Venus was -0.44, and the value of r for Vivian’s function was 0.88.

Who has the BEST model for his or her data.

Answer:

B) Victor

Step-by-step explanation:

A positive value for r implies a positive linear correlation, while a negative value for r implies a negative linear correlation. The

closer |r| is to 1, the stronger the correlation, and the stronger the correlation, the more reasonable the data model. Since |–0.91| =

0.91, |0.73| = 0.73, |–0.44| = 0.44, and |0.88| = 0.88, the person with the most reasonable model for his or her data is B) Victor!

Hope this helps, have a good day. c;
