Effect of formulation changes for a lens coating

Reference no: EM131015082

The data set odor .txt contains three responses gathered from a factorial design (described in Chapter 9). The purpose of the experiment was to study the effect of formulation changes for a lens coating on three primary responses: odor, hardness, and yellowing. The odor of each formulation was ranked on a scale of 1-10 (with 10 being the smelliest) by 10 people and then all 10 rankings were averaged to obtain the value of odor for the analysis. The purpose of this portion of the analysis is to look for relationships between the formulation odor and the two other responses.

(a) Make scatter plots of the data.

(b) Do the responses appear to be related to the odor?
