Question

CAN SOMEONE HELP ME WITH THIS QUESTION???? I NEED HELP QUICK!!!!!!!!!

Answer 1

1. r closest to 1: figure

2. No linear relationship: Figure 1

3. r equal to 1: Figure 3

Step-by-step explanation:

Correlation is the link between two variables or things"

• When one quantity is increasing and the other is also increasing then the correlation co-efficient is positive
• When one quantity is increasing and the other is decreasing then the correlation is negative.

Now for the scatter plot of a correlation:

• If the data points are close to a best fit line then the correlation is strong
• If the data points follow a linear relationship i.e. a straight line then the correlation is 1 or -1 depending on the sign of correlation
• If the data points are more scattered then they have least correlation

Correlation coefficient closest to 1:

We can see in figure 4 that the data points are gathered across a line but not a perfect line and both the quantities are increasing so the correlation coefficient is close to 1.

Least Evidence of linear relationship:

Figure 1 can be observed to conclude that the data points are scattered on whole scatter plot hence creating no relationship

Correlation coefficient equal to -1:

We can see in figure 3 that one quantity is increasing and the other is decreasing and the data points are forming a line so the correlation coefficient will be -1
