Exploration and description

Rainfall and temperature data were obtained from Weather South Africa for the duration of the experiments. These are summarised here. Such data are important to collect as they can help in interpreting the experimental results.

For the purpose of this case study only Study 1 at Ukulinga will be used to demonstrate methods of analysis. Two variables, dry corm weight per plant and number of corms per plant, are chosen for further analysis. We shall start with dry corm weight.
