RESPOND: Module 12 Participation Discussion - The roles of variables A 1 Respond to the following discussion and reply to at least one other student's response. Let's say you have two variables say forearm diameter and grip strength and you initially use forearm diameter as the explanatory variable, x ,and grip strength as the response variable, y, when constructing a best fit line. Let's say you get the following equation... grip strength = b + m-(forearm diameter) That is, given a forearm diameter, one can predict the grip strength. The "*" above "grip strength" means that it is a predicted value from the forearm diameter. For example, let's say we have the following equation to predict grip strength from forearm diameter. grip strength = 16.62 + 4.43-(forearm diameter) So, if a forearm has a diameter of 8 inches, then the predicted grip strength would be grip strength = 16.62 + 4.43-8 = 18.82 pounds Now let's say you want to switch the roles of the variables and now you want to use grip strength as the explanatory variable, X, and forearm diameter as the response variable, y. Discuss if it is appropriate to use this same equation to predict forearm diameter from grip strength. That s, given a grip strength is it appropriate to predict forearm diameter by substituting the given grip strength into the above equation and solving for the forearm diameter? grip strength = b + m-(forearm diameter) If we used the same example as before it would be grip strength = 16.62 + 4.43-(forearm diameter) and solving for forearm diameter would result in 16.62 1 , + 143 143 (grip strength) forearm diameter = So, is it appropriate to use this equation to predict the forearm diameter from grip strength?
