Final answer:
Without scatterplots, it's not possible to accurately match provided correlation coefficients. Yet, a correlation coefficient of -0.90 signals a stronger relationship than -0.50, as coefficients closer to -1 or +1 indicate stronger relationships, irrespective of the sign.
Step-by-step explanation:
The question is asking to match correlation coefficients with corresponding scatterplots, but without the actual scatterplots provided, it's not possible to make the match accurately. However, addressing the 14th question, which asks which correlation coefficient indicates the strongest relationship between two variables, we can explain that correlation coefficients can range from -1 to 1. A correlation coefficient of -1 indicates a perfect negative linear relationship, and a coefficient of 1 indicates a perfect positive linear relationship. The value of 0 means there is no linear correlation between the variables. Therefore, the correlation coefficient that is furthest away from zero, either positive or negative, indicates the strongest relationship. Between -.90 and -.50, -.90 is further from zero, thus it indicates a stronger relationship between the two variables, despite being negative. It's important to note that the sign indicates the direction of the relationship, not the strength.
