To determine the weakest correlation among the given options, we need to understand what correlation coefficients represent. Correlation coefficients range from -1 to 1, where:
- – A value of 1 indicates a perfect positive correlation.
- – A value of -1 indicates a perfect negative correlation.
- – A value of 0 indicates no correlation.
In the options provided:
- a) 0.24
- b) 0.22
- c) 0.19
- d) 0.96
The values 0.24, 0.22, and 0.19 are all positive correlations, while 0.96 suggests a strong positive correlation. Among the three positive values, 0.19 is the smallest, indicating that it represents the weakest correlation. Therefore, the answer is:
