No. The units of the two variables in a correlation will not change the value of the correlation coefficient.

Positive correlation is a relationship between two variables in which both variables move in tandem that is in the same direction.

If two variables are highly correlated, the Pearson correlation will be close to -1.0 or +1.0. A correlation of zero shows no relationship.

Correlation is a measure of the degree to which two variables change together. Positive correlation means that the variables increase together and decrease together. Negative correlation means that one variable increases when the other decreases.Correlation does not imply causality.Correlation is a measure of the degree to which two variables change together.

It mean that there is no correlation between the two variables. The variables are the same.

A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.

Correlation is a statistical measure of the linear association between two variables. It is important to remember that correlation does not mean causation and also that the absence of correlation does not mean the two variables are unrelated.

No. The units of the two variables in a correlation will not change the value of the correlation coefficient.

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.

Positive correlation is a relationship between two variables in which both variables move in tandem that is in the same direction.

Correlation refers to the extent to which two variables relate to one another. This is often referred to in scientific studies.

"If coefficient of correlation, "r" between two variables is zero, does it mean that there is no relationship between the variables? Justify your answer".

a zero correlation means that there is no relationship between the two or more variables.

If two variables are highly correlated, the Pearson correlation will be close to -1.0 or +1.0. A correlation of zero shows no relationship.

Nothing, because they cannot. You need at least a pair of data for two variables before correlation can be calculated. That means at least four numbers.
