1. Positive but not perfect: Figure 4
2. Correlation coefficient equal to 1:
3. Strongest linear relationship: Figure 2
Step-by-step explanation:
"Correlation is the link between two quantities"
The relationship is said to be positive if both are increasing and said to be negative if both are opposite i.e. one is increasing and one is decreasing.
In the Given figures
1. Positive but not perfect linear relationship:
The perfect positive relationship is when both the quantities are increasing and the scatter points are in a line that grows linearly. Here, The data set in figure 4 has positive correlation but as the points are scattered around a line so the correlation is positive but not perfect.
2. Correlation equal to 1
The correlation in figure 1 is the perfect correlation as the data points follow a straight line and both the quantities are increasing.
3. Strongest linear relationship:
The relationship in figure 2 has the strongest in figure 2 as the data points are more close to the best fit line
