The following data represent tea leaf pluckings from sixteen different plots of tea bushes intended for experimental use in Ceylon. The pluckings are divided into four different treatment groups, and we wish to determine if one of the treatments is more effective. Test this using 1% significance, assuming that these samples are drawn from normal populations with equal variances. These values are also from Statistical Methods for Research Workers by Ronald Fisher, but the data were gathered by T. Eden. Treatment 1 Treatment 2 Treatment 3 Treatment 4
