A textile scientist has used a 24 design, with half the points run once and half

the points run twice. Those points in the 24−1 fraction with defining relation

I = 𝟏𝟐𝟑𝟒 were run twice and those points in the 24−1 fraction with defining

relation I = −𝟏𝟐𝟑𝟒 were run once. The order in which these tests were performed was determined by randomization. The scientist asks you to obtain

estimates of all the main effects and interactions with their associated standard errors. How would you do this?
