are weight gains a dependent variable is length gain a variable weight gain and length are correlated which is a correlated variable? what is the relationship of length gain and weight gain what model is used to describe weight gain and length gain weight gain vs length is length gain a dependent variable weight gain and length gain can be combined weight gain and length gain is correlated i have weight gain and length gain is weight gain and length correlated weight gain vs length gain in weight gain if weight gain and length gain together, what is the model if length and weight gain is correlated, do they differ for length and weight gain are weight gain and length a dependent variable in weight gain analysis is weight gain a covariate variable what is a correlated variable on fish stocks is weight gain correlated with length are weight gain and length correlated?
