shown below are the scatter plots for four data sets. answer the questions that follow.\n(a) which data set appears to show a negative linear relationship between its two variables? (choose one)\n(b) which data set appears to show a positive linear relationship between its two variables? (choose one)\n(c) which data set appears to show no relationship between its two variables? (choose one)\n(d) which data set appears to show a nonlinear relationship between its two variables? (choose one)
Answer
Explanation:
Step1: Identify negative linear relationship
In a negative - linear relationship, as one variable increases, the other decreases in a linear fashion. In Figure 2, as the x - values increase, the y - values decrease in a somewhat straight - line pattern.
Step2: Identify positive linear relationship
In a positive linear relationship, as one variable increases, the other also increases in a linear fashion. In Figure 4, as the x - values increase, the y - values increase in a somewhat straight - line pattern.
Step3: Identify no relationship
In a data set with no relationship, the points are scattered randomly with no discernible pattern. In Figure 1, the points are randomly scattered with no clear increasing or decreasing trend.
Step4: Identify nonlinear relationship
In a nonlinear relationship, the points follow a non - straight - line pattern. In Figure 3, the points form a U - shaped pattern, which is a nonlinear relationship.
