A 2 x 2 factorial experiment comparing 2 types of seed and 2 root extracts. There are 5 or 6 replicates in each
of the 4 treatment groups, and each replicate comprises a number of seeds varying between 4 and 81. The response
variable is the proportion of seeds germinating in each replicate. (Crowder, 1978, Table 3).References
