This recognition and recall practice is based on p.31 of the Dowdall, Logio, Babbie and Halley text.Click on any of the question numbers for jeanne's response.

- What level of measurement are we using if we measure education by the highest grade completed?
One plausible response:

We are using interval measurement because "highest" does not refer to simply ranking the grades. It refers to which grade the subject should choose to report: the highest. And grade levels traditionally represent one-year intervals. That really makes it interval measurement where we're measuring the number of years completed.

This was trickly. Heh! Heh!

- What level of measurement are we using if we measure age by asking the subject to give us his/her actual age?
One plausible response:

Age is measured in years, unless you're less than 2 years old. So this is interval measurement. No tricks!

If you're under 2, and your mother gives your age in months, is that interval?

- What level of measurement are we using if we measure social class by asking the subject to choose the yearly income bracket into which he/she fits?
One plausible response:

When the term "bracket" is used, that's another term for category. Here we're not measuring the actual income in $; we're measuring whether you're in a high or low bracket. Brackets can be ordered or ranked. But they don't give interval data. This is ordinal measurement.

- What level of measurement are we using if we measure class by asking the subject to choose the weekly income category into which he/she fits?
One plausible response:

We're still asking here for actual income. That's interval. It doesn't matter whether it's annual or weekly. Notice how this is similar to the years, months problem, in measuring age.

- What level of measurement are we using if we measure education by asking the subject to state the number of years of school completed?
One plausible response:

This is interval measurement. School years are equal intervals. No tricks, honest!

Yes. Months are equal intervals. It's interval measurement.
