Levels of Measurement
Nominal: “In name only”
Data only describes a quality or name but would not make sense to put the data in any order because no one is “greater” or “less” than the other
: Data can be put in ORDER but the actual differences between values either can’t be determined or is meaningless.
: Just like ordinal BUT, there are meaningful differences between the daa values. There may not be an intrinsic ZERO or STARTING POINT. Differences are meaningful but ratios are not.
: Highest level of measurement. We can order, take differences and also find the ratio. It makes sense that one data value is “twice as large” as another for example. IT INCLUDES AN INHERENT ZERO OR STARTING POINT.
: Organizes, pictures, and summarizes information from
samples or populations.
: involves methods of using information forma sample to draw conclusion regarding the population.
