7. The way in which the data can be recorded
Continuous data
100 0C - 0 0C = 100 0C
100 0C - 1 0C = 99 0C
100 0C > 90 0C Interval data
Operations valid :
But, <, >,+. -
100 0C * 4 ≠ 4000C
100 K- 0 K= 100 K
100 K – 1 K = 99 K
100 K > 90 K Ratio data
Operations valid :
And, <, >,+. -, *, /
100 K * 4 = 400 K
8. Measurement Scales/ Level of Measurement
>,<,+,-,/,*
>,<,+,- e.g. temperature, as
measured in K
>,< No absolute zero
e.g. temperature, as measured in o F or o C
Distances have no meaning
e.g. Socioeconomic status
cannot quantify or even rank order e.g. gender, race, color, city, etc.
