CA Foundation · Quantitative Aptitude · Correlation and Regression
A scatter diagram shows points lying close to a straight line sloping downward from left to right. The correlation is best described as:
The correlation is high negative linear correlation. The line slopes downward, so Y falls as X rises, and the points lie close to the line, showing a strong linear association.
- AHigh positive linear correlation
- BHigh negative linear correlationCorrect
- CLow positive correlation
- DZero correlation
Explanation
A downward-sloping band means that as X increases, Y decreases, so the correlation is negative. Points lying close to the line indicate a strong, high degree of association. Hence it is high negative linear correlation.
Did you get it right without looking?
One question tells you little. A timed set on Correlation and Regression shows your real accuracy, how long you take and where you lose marks.
