Answer:
Option b. Perfect correlation is the correct option.
Explanation:
- if the scatter diagram is drawn the scatter points lie on a straight line then it indicates a perfect correlation.
- Perfect correlation can be divided into positive and negative correlations.
- Perfect Positive correlation occurs when the scatter points make a straight line from 0 to the highest Y & highest X position.
- Perfect Negative correlation occurs when scatter points make a straight line from the higher value on the Y-axis to a higher value on the X-axis of the scatter diagram or scatterplot.
