Step 1: Understand the problem
We are given four correlation coefficients (r-values) and asked to identify the one that represents the strongest correlation. The r-value can range from - 1 to 1, where - 1 indicates a perfect negative linear relationship, 1 indicates a perfect positive linear relationship, and 0 indicates no linear relationship. The stronger the correlation, the closer the r-value is to - 1 or 1.
Step 2: Compare the given r-values
Of the given options, we have the following r-values: A. - 0.5 B. - 0.7 C. - 0.4 D. - 0.6
Final Answer
The r-value that represents the strongest correlation is - 0.7 (option B).
