Homework Answers
The levels of measurement in statistics are the mathematical precision with which the values of a variable can be expressed.
The nominal level of measurement, which is qualitative, has no mathematical interpretation.
The ordinal, interval and ratio levels of measurement are quantitative levels of measurement which are more precise mathematically.
