how are the two random variables different what is the measure of the correlation between two variables of unequal sizes? how closely correlated is x how to measure correlation among two variables how closely correlated is two variables of unequal size why do the variables have unequal dimension how many rows do x and y have correlation amongst two variables how is correlation measured in a data set how many rows and columns are in a linear correlational equation? how does pearson's rank measure the correlation of the two variables what is the relationship between y and x? what size are the two random variables what is the difference between x and y in r how to figure out the correlation between two variables which variables are equally correlated in a correlation problem? which random variable does r require to be measured pearson's correlation definition how many columns does the x have in a row what is the correlation between x and y
