shown below are the scatter plots for four data sets. answer the questions that follow. (a) which data set appears to show a nonlinear relationship between its two variables? (b) which data set appears to show a positive linear relationship between its two variables? (c) which data set appears to show a negative linear relationship between its two variables? (d) which data set appears to show no relationship between its two variables?
Answer
Explanation:
Step1: Analyze nonlinear relationship
In Figure 4, the points follow a curved - shaped pattern, indicating a nonlinear relationship.
Step2: Analyze positive linear relationship
In Figure 3, as the x - values increase, the y - values generally increase in a linear fashion.
Step3: Analyze negative linear relationship
In Figure 1, as the x - values increase, the y - values generally decrease in a linear fashion.
Step4: Analyze no relationship
In Figure 2, the points are randomly scattered with no clear pattern of increase or decrease.
Answer:
(a) The data set in Figure 4 (b) The data set in Figure 3 (c) The data set in Figure 1 (d) The data set in Figure 2
