Final answer:
If the scatter plot points lie on a straight line, it denotes a perfect correlation.
The answer is B
Explanation:
In a scatter diagram, if the points lie on a straight line, it indicates a Perfect Correlation. The term 'Perfect Correlation' in statistics refers to a scenario where the relationship between two variables is exactly linear, that is, all data points perfectly lie on a straight line.
This perfect linear relationship can be either positive or negative - in a perfect positive correlation, as one variable increases, the other increases at the same rate, whereas in a perfect negative correlation, as one variable increases, the other decreases at the equivalent rate
. This straight line trend is often revealed by a scatter diagram, which is a visual representation of the correlation between the two sets of data.
