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

Keywords: Correlation, Scatter plot

<h3>Explain why it is helpful to know the basic function shapes and discuss some ways to remember them. </h3>
  • Knowing the basic function shapes and discuss some ways to remember them is helpful because this is useful tools in the creation of mathematical models because we constantly make theories about the relationships between variables in nature and society. Functions in school mathematics are typically defined by an algebraic expression and have numerical inputs and outputs.
