which r - value represents the weakest correlation?\n-0.75\n-0.27\n0.11\n0.54

Explanation:

Step1: Recall correlation - r - value concept

The strength of a correlation is determined by the absolute value of the correlation coefficient (r). The closer (|r|) is to 0, the weaker the correlation.

Step2: Calculate absolute values

For (r=- 0.75), (|r| = |-0.75|=0.75); for (r = - 0.27), (|r|=|-0.27| = 0.27); for (r = 0.11), (|r|=|0.11| = 0.11); for (r = 0.54), (|r|=|0.54| = 0.54).

Step3: Compare absolute values

We compare (0.75), (0.27), (0.11), and (0.54). Since (0.11<0.27<0.54<0.75), the (r - value) with the smallest absolute value is (0.11).

Answer:

0.11
