which r - value represents the strongest negative correlation? 0.9 0.38 -0.22 -0.7
which r - value represents the strongest negative correlation? 0.9 0.38 -0.22 -0.7
Answer
Explanation:
Step1: Recall correlation - r - value concept
The absolute value of the correlation coefficient (r) measures the strength of the correlation. For negative correlations, we consider the absolute - value of (r) among negative values.
Step2: Compare absolute values of negative r - values
We have two negative (r) - values: (\vert - 0.22\vert=0.22) and (\vert - 0.7\vert = 0.7). Since (0.7>0.22) and we are looking for the strongest negative correlation.
Answer:
- 0.7
