Question

swer the questions that follow. the same response may be the correct answer for more than one question. 1. which data set shows the least evidence of a linear relationship? 2. for which data set does the correlation coefficient r appear to be equal to 1? 3. for which data set is the correlation coefficient r closest

Explanation:

Step1: Analyze linear - relationship evidence

In a scatter - plot, if the points are randomly scattered with no discernible pattern of a straight - line, it shows little linear relationship. In Figure 1, the points are more randomly distributed compared to the others.

Step2: Understand correlation coefficient r = 1

A correlation coefficient r = 1 indicates a perfect positive linear relationship. In Figure 3, the points lie almost perfectly on an upward - sloping straight line, suggesting r is close to 1.

Answer:

1. The data set in Figure 1
2. The data set in Figure 3
