When we fall into the trap of believing that terms have real meanings we are guilty of:

Most social scientists would not accept the conceptualization of prejudice as foot size because such a measurement lacks:

Number of arrests would be an example of an interval measurement

A split-half reliability test taps the idea of the general stability of the instrument over time.

Professor Tilton measured the variable "feelings toward drafting women" with the categories strongly agree,agree,indifferent,disagree,and strongly disagree.Professor Tilton was using the level of measurement.

The test-retest method assumes that the phenomena under study does not change.
