What are the four levels of measurement choose 4 answers?

Within your dataset, you'll have different variables—and these variables can be recorded to varying degrees of precision. This is what's known as the level of measurement. There are four main levels of measurement: nominal, ordinal, interval, and ratio.

What are the characteristics of the 4 scales of measurement?

It is an extension of the interval scale, therefore satisfying the four characteristics of the measurement scale; identity, magnitude, equal interval, and the absolute zero property. This level of data measurement allows the researcher to compare both the differences and the relative magnitude of numbers.
