This year students were introduced to both the R statistical programming language (open source, free) and GenStat (commercial). Either tool can be used for this assignment.

For R it is best to work with simple plain text files containing "Tab Separated Variables", like these:

• lilies.txt - Question One
• asthmatics.txt - Question Two
• arabidopsis.txt - Question Three
• mushrooms.txt - Question Four
• regression.txt - Question Five
• wheat.txt - Question Six

You can also download all the data in a single Microsoft Excel spreadsheet (one dataset per worksheet) for use with GenStat:

• MOAC_CH923_Data_Analysis.xls - Questions One to Six

N.B. Some column names in the Excel file have an exclamation mark at the end - this tells GenStat to treat them as factors (categorial data).

P.S. Files for the GenStat introduction session are on the lecture notes page.
