Hi , Is anyone could help me of my little problem of Minitab project?
when I use DOE analysis the data, the graph for normal distribution of residual is unusual, so I try to transform it. However, the p value become smaller than before and there is nothing change for the graphs, only cut out several significant point.
I don't know what to do next.
Does the data result in this problem, maybe the data I analysis is not right originally??
Guys, Please help me to find it out~~
Thanks
