are highly correlated variables uncorrelated are correlated variable very uncorrelated which variable is highly correlated and which is uncorrelated why do most variables in the eda work together ___ is highly correlated why are the sums and differences of highly correlated variables almost uncorrelated? is it important to give a reference for a highly correlated variable why is variance correlated what is a mathematical reference is sum and difference correlated why is summing and difference important which of the following is a reference for the sum and difference of highly correlated variables? when a variable is highly correlated but uncorrelated what is the difference between the sum and the difference of highly correlated variables? are variables uncorrelated why is the sum and difference uncorrelated are sums and differences of variables correlated what's the sum and difference in a correlated variable what is the inverse of the sum and difference of highly correlated variables? how to explain why an equation is uncorrelated
