Description Spinage heated to 90 or 100 degrees Celcius was vacuum packed and stored for 0, 1 or 2 weeks before the packs were opened and chill stored in normal atmosphere for 0, 1 or 2 days. Then the colour was measured on a Hunter Lab. Two of the colour coordinates, a and b (measuring respectively something like red and yellow colour), were recorded and are given in the data set below. The variable batch is a blocking variable referring to two batches of spinage. Number of observations: 36 Variable                Description batch Values A,B (blocking factor) temp Values 90,100(celcius) weeks Values 0,1,2 (pre-storage time) days Values 0,1,2 (post-chill-storage time) a measure of red colour intensity b measure of yellow colour intensity Source The Royal Veterinary and Agricultural University, Denmark. Analysis Randomized block (fixed three-way treatment with interaction, random block) for each of the two variables. Optimized for Microsoft Internet Explorer 6.0 for Windows webmaster
