Question

Which is most likely the correlation coefficient for the set of data shown?

Answer 1

Answer:

The answer will be 0.872

Step-by-step explanation:

• The coefficient of correlation of a relapse line is a proportion of how intently the line accommodates data.  Negative coefficients depicts to diminish lines; positive coefficients depicts to expand lines.  
• The closer a coefficient is to +1 or - 1, the better the fit; an ideal positive fit is r=1 and an ideal negative fit is r=-1.  
• We can find in the chart that the line is near our information, so it is an entirely solid match.  
• The line is expanding; this implies we need a relationship coefficient that is near 1.
