Question

answer the questions that follow. here are scatter - plots for four data sets. (a) which data set appears to show a negative linear relationship between its two variables? select (b) which data set appears to show a positive linear relationship between its two variables? select (c) which data set appears to show no relationship between its two variables? select (d) which data set appears to show a nonlinear relationship between its two variables? select

Explanation:

Step1: Analyze Figure 1

As x - values increase, y - values decrease. So it shows a negative linear relationship.

Step2: Analyze Figure 2

As x - values increase, y - values increase in a non - straight line pattern. So it shows a non - linear relationship.

Step3: Analyze Figure 3

As x - values increase, y - values increase in a straight - line pattern. So it shows a positive linear relationship.

Step4: Analyze Figure 4

The points are scattered randomly. So it shows no relationship.

Answer:

(a) Figure 1
(b) Figure 3
(c) Figure 4
(d) Figure 2
