Correlation

Example:

Imagine you want to study the correlation between driving speed and fuel efficiency of cars.

Data:
Car A: Average speed of 60 mph, fuel efficiency of 30 miles per gallon (mpg)
Car B: Average speed of 70 mph, fuel efficiency of 28 mpg
Car C: Average speed of 50 mph, fuel efficiency of 32 mpg
Car D: Average speed of 80 mph, fuel efficiency of 25 mpg


Observation:
From the data, we observe that as the average driving speed increases, the fuel efficiency tends to decrease. This suggests a negative correlation between driving speed and fuel efficiency.

Conclusion:
There is a negative correlation between driving speed and fuel efficiency, indicating that higher driving speeds generally result in lower fuel efficiency.
