  13. CLASSIFY DATA BY LEVEL(nominal, ordinal , interval, ratio)

  14. CLASSIFY DATA BY LEVEL(nominal, ordinal , interval, ratio) • The top 5 teams in the college football poll released January 3, 1998 are • 1. Michigan • 2. Nebraska • 3. Florida State • 4. Florida • 5. UCLA

  15. CLASSIFY DATA BY LEVEL(nominal, ordinal , interval, ratio) • The top 5 teams in the college football poll released January 3, 1998 are • 1. Michigan • 2. Nebraska • 3. Florida State • 4. Florida • 5. UCLA • ORDINAL (ordered)

  16. CLASSIFY DATA BY LEVEL(nominal, ordinal , interval, ratio) • The 4 major professional tennis tournaments are: Australian Open, French Open, Wimbledon, US Open

  17. CLASSIFY DATA BY LEVEL(nominal, ordinal , interval, ratio) • The 4 major professional tennis tournaments are: Australian Open, French Open, Wimbledon, US Open • NOMINAL (names only)
