4. Irish Centre for High End Computing (ICHEC) - Data Mining Example Large bins show global features, tips fall off quickly so perhaps this is not a very expensive restaurant.
5. Irish Centre for High End Computing (ICHEC) - Data Mining Example Smaller bins show local features, tips tend to be rounded to the nearest 50 cents or dollar.
6. Irish Centre for High End Computing (ICHEC) - Data Mining Example Looking at the correlation between variables (r) and checking to see who gives more or less than the ‘average’ tip of 18% of the bill.
7. Irish Centre for High End Computing (ICHEC) - Data Mining Example ‘ Conditioning’ or ‘Drilling down’ to explore more complex relationships within the data.
