Reading from text, Chapter 15, first part

Chapter 15: 15.1 - 15.3

15.1

What 2^k designs are; introduce the terminology of "high" and "low" levels

2^k designs are exploratory, part of a strategic approach

15.2

All the effects in these designs are 1 df comparisons.

Meaning of the comparisons

Calculating SS of the comparisons; these are "G" cells; SSE = SST - all the effect SSs

2³ example & a geometric interpretation that may or may not be helpful

15.3

Do it again for "S" cells

Can't get SSE unless assume some effects = 0

Graphical method to determine which effects seem close to 0, and represent noise only
