1.3 Data sets used 41.3.2 Repeated measures on ratsGrowth curve data on the body weights of rats are taken from Box [1950]. A total of 27rats was divided randomly into 3 groups of 10, 7 and 10, respectively. Group 1 were keptas a control, group 2 had thyroxin and group 3 had thiouracil added to their drinkingwater. Five weekly measurements were taken on each individual and the raw results areshown in Figure 1.1.Weight60 80 100 120 140 160 180CCCXTTCTCCXTCTCXTTCXXCXTCTXCXTTXCXCXCCXTCXTTTXCCXCXCCXCXTTTT0 1 2 3 4WeekFig. 1.1.

Much of the wool is produced from wethersand most major producers have traditionally used a particular strain or bloodline. Toassess the importance of bloodline differences, many wether trials were conducted. Onetrial was conducted from 1984 to 1988 at Borenore near Orange. It involved 35 teamsof wethers representing 27 bloodlines.
