Aim:    To produce a statistical report testing a number of hypotheses on a population of yellowhammers

Specific Tasks:
•    Use the data set in the Excel file (yellowhammers.xls) as the basis for your scientific report.
•    Provide a brief background/introduction about yellowhammer conservation.
•    Formulate and state clearly FOUR experimental hypotheses of your own choosing (with accompanying null hypotheses in each case), relating to the data set.
•    Identify appropriate statistical techniques in order to test your four hypotheses. You should use at least three different tests but may use the same test more than once if appropriate. You should justify why you have chosen the particular test in each case and include a brief discussion of any assumptions or limitations of your tests.
•    Undertake the analyses using MINITAB and present the findings using appropriate text and accompanying figures.
•    Interpret the findings and discuss in context with other studies.
•    Comment on the limitations of the study, including the experimental design, and make suggestions for how the investigation could have been improved i.e. is there any information missing that would have improved the strength of your analyses? Are you able to recommend a variation of the experimental design that could have provided more reliable/accurate data?

Sources of Information:
•    Lecture notes and consultation with subject area staff
•    Resource list
•    Library resources (see reading list on module pack)
•    Help section on MINITAB
