Question #23 / 25 Below are four bivariate data sets and the scatter plot for each. (Note that each scatter plot is displayed on the same scale.)

The same response may be the correct answer for more than one question 1. In which data set is there evidence of a strong nonlinear relationship between the two variables? Choose one 2. Which data set indicates a perfect negative linear relationship between its two variables? Choose one 3. Which data set has an apparent negative, but not perfect, linear relationship between its two variables? 4. Which data set indicates the strongest positive linear relationship between its two variables? Choose one Clear Undo HelpExplanation / Answer
Question 1 :
The data set 4 (figure 4 ) shows random pattern ( i.e. non -linear pattern) and remaining three data set shown linear pattern.
Correct Answer : In the m, n data set there is a evidence of a strong non-linear relationship between two variables.
Question 2 :
When values of data set lies on straight line in an downward direction, then there is perfect negative linear relationship between two variables.
None of figures shows straight line in an downword direction.
Correct Answer : None of data set indicates a perfect linear relationship between two variables.
Question 3.
The figure 2 shows linear pattern ( but not straight line)and points lies in downword direction.
Correct Answer : The u,v data set has an apparent negative but not perfect linear relationship between two variables.
Question 4 :
Figure 3 shows all point lies on straight line and direction is an upward. Hence there is perfect positive (strongest) relationship between two variables.
Correct Answer : The w,t data set indicates the strongest positive linear relationship between two variables.
