Barleyheight: Comparison of genotypes and checking time trend
In gpk: 100 Data Sets for Statistics Education

Description Usage Format Details Source Examples

Data are plant height of barley measured in cm. Averaged over 4 replicates for 15 genotypes. It is of interest if there is any difference in genotypes and also if there is any time trend in heights for the same genotype. Further, one may check if trend is similar across genotypes. It is of interest to explain height using weather information.
