My life's Adventure

I did some calculations this morning.

I did some calculations this morning following the teachers notes. These checked out with the software's analysis, so no mistakes were made with the software data entry or the calculations that I did with a word processor and a calculator. The data relate to a machine tool process involving speed of the tool, geometry, and cuting angle. I am supposed to figure out which has more effect on the life of the tool which is our response variable. In schizophrenia the response variable is not as clear and is more dynamic and is more likely a quality of life variable. In these studies of dugs the experimental design is also statistical.
