Document Summary

Involves numbers that represent names (jersey names number 12 and number 3) Treat nominal data as if its numerical then you will get a nonsense result. Ordinal scales: involves ranking how far in between (one comes in first and one comes in second but it doesn"t tell people how much first beat second by, no equal spacing) Someone decides to rate someone 88 and 93. Yes 93 is higher than 88, but its 5 higher but it means something. Interval: same distance between intervals there is no true zero . Implication: cannot be twice as intelligent or third as conscientious. There is a true zero, there is no negative. Height, points and age is a ratio scale. He scored twice as many points as she did.
