\\\\(\\Rightarrow\\\\) If the correlation coefficient of two variables is zero, it signifies that there is no linear relationship between the variables. However, this is only for a linear relationship; it is possible that the variables have a strong curvilinear relationship.\\\\(\\Rightarrow\\\\) When the value of r is close to zero, generally between \\\\(-0.1\\\\) and \\\\(+0.1,\\\\) the variables are said to have no linear relationship or a very weak linear relationship. \\\\(\\Rightarrow\\\\) For example, suppose the prices of coffee and of computers are observed and found to have a correlation of \\\\(+.0008;\\\\) this means that there is no correlation, or relationship, between the two variables.\\\\(\ herefore\\\\) We can say that, if the value of any regression coefficient is zero, then two variables are \\\\(Independent\\\\).
