Correlation is the 
relationship that exists 
between two or more 
variables. 
If two variables are 
related to each other in 
such a way that change 
increases a 
corresponding change in 
other, then variables are 
said to be correlated.

The effect of 
correlation is to 
reduce the range of 
uncertainty of our 
prediction . 
The prediction based 
on correlation 
analysis will more 
reliable and near to 
reality.
