In surveys, we find data that is "correlated", meaning one factor may have not directly interfered with another factor, yet the more of the X factor we have, the more of the Y factor we are likely to have (positive correlation).
For example, if a survey says that teenage girls who do not eat dinner with their family are more likely to become pregnant before age 17, then there is a positive correlation between teen girls not eating dinner with family & teen pregnancy.
Not eating dinner with one's family will not causepregnancy, but there is a strong relationship between the two. <--This is a positive correlation
To sum it up, correlation does not equal causation.
Relation, on the other hand, is cause and effect (almost the opposite of correlation).
Relation is cause & effect.
The correlation coefficient is zero when there is no linear relationship between two variables, meaning they are not related in a linear fashion. This indicates that changes in one variable do not predict or explain changes in the other variable.
partial correlation is the relation between two variable after controlling for other variables and multiple correlation is correlation between dependent and group of independent variables.
Biochemical correlation refers to the statistical relation between two or more biochemical variables.

Positive correlation has a positive slope and negative correlation has a negative slope.
by all means of
Relation between phase difference and path difference is path difference/wavelength=phase difference/2*pi
The difference between multicollinearity and auto correlation is that multicollinearity is a linear relationship between 2 or more explanatory variables in a multiple regression while while auto-correlation is a type of correlation between values of a process at different points in time, as a function of the two times or of the time difference.
The Matthew correlation coefficient considers true and false positives and negatives. The specificity correlation only considers the true classes or rejections.

Difference?? There is no relation.
The relation between electron affinity and atomic radius is inversely proportional.
