Question

Suppose that there is a positive correlation between the variables k and l. If l is 75 when k is 7, which of these is most likely to be the value of l when k is 14

Answer 1

There is a positive correlation between the variables k and l.

We can express this as:

k $\alpha$I

Mathematically, we can write this as:

k = aI (Where a is the constant of proportionality 

If l is 75 when k is 7

⇒ 7 = 75a

a = $\frac{7}{75}$


∴ k =  $\frac{7}{75}$ I


I = $\frac{75}{7}$k

When k = 14


I = $\frac{75}{7}$ x 14

  = 150


I is likely to be 150
