farms: Size of Plants at Five Different Locations

Description

The size of plants has been measured on 24 farms in five different locations. There is various Nitrogen content in the soil within each of the 24 farms. This data set illustrates spatial pseudo-replication, since the five measurements made on each farm are probably dependent, coming from the same farm.
