Which correlation coefficient corresponds to the best-fit line that most closely models its set of data?
a)

-0.15


b)

-0.87


c)

0.13


d)

0.84

Respuesta :

The answer for this question is c

⇒Two sets of data are said to be closely modeled or related , if with increase in one other increases and with decrease in one other also decreases.

⇒Value of Correlation Coefficient(r), lies between

  -1 ≤ r≤1

⇒Value of r is higher ,that is nearer to 1, if there is strong correlation between two variables means Strong association between two variables.

⇒Option D:→ 0.84------Showing strong Correlation between two variables(r)
