Design of Experiments - Paper Helicopter Example

[mark1505]

Having completed my paper helicopter experiment and inputted the information into the Minitab 18 software i am slightly worried that two of the categories:- Body length and Body width do not appear in the final interaction plot or optimization plot graphs at the final stage. I would really appreciate anybodys advice or help on this subject. Best regards
