Times and winners of the London Marathon (1981-2009).
This data set lends itself to a range of classroom investigations and the TI-Nspire is an ideal tool for analysing and displaying the data.
Who has won the most races? Which countries supply most winners? Can you compare men's and women's times? Are runners getting faster? Are women improving faster than men? How often are there new record times?
A tns file provides the data and teacher notes provide ideas and hints for investigations.
