Description: Results of Experiment measuring top shrinkage under 4 treatments (untreated, alcoholic potash (15sec), alcoholic potash (4min), alcoholic potash (15 min)), measured after 7 levels of numbers of revolutions (200:1400 by 200), over 4 experimental runs (blocks). Conducted as a split-plot experiment with whole plot factor=treatment, sub-plot factor = # revolutions in 4 blocks (runs) Variables/Columns Run 8 Treatment 16 /* 1=untrt, 2=ac(15s), 3=ac(4m), 4=ac(15m) */ Number of Revolutions 21-24 Top Shrinkage 29-32
