Unformatted text preview: e analyzed. This tipping data is a great start for a data analysis course because it is clearly a pilot study. There is no temptation to make inference from the data, and emphasis should be on poking around the data to formulate hypotheses, that might be used to design a later study. Tips are also something that we all confront in our daily life, so we can relate to the data, and use personal experience to digest some of the findings. 9 Eg Tips 1 9 9 CASE STUDY: Classifying Australian Leptograpsus Crabs 1 Data Description This data was described in Campbell & Mahon (1974). It contains measurements on rock crabs of the genus Leptograpsus. One species L. variegatus had been split ￿ into two new species, previously grouped by color form, orange and blue. Preserved specimens lose their color, so it was hoped that morphological differences would enable museums specimens to be classified. There are 50 specimens of each sex of each species, collected on sight at Fremantle, Western Australia. Each specimen has measurements on Frontal Lip (FL), in mm Rear Width (RW), in mm Length of midline of the carapace (CL), in mm Maximum width of carapace (CW), in mm Body Depth (BD), in mm. The primary question here is “How do we distinguish between species and sex based on these five morphological measurements.” 9 CASE STUDY: Classifying Australian Leptograpsus Crabs 1 Data Eg Crabs Description This data was described in Campbell & Mahon (1974).
