Prospective employees were asked how many jobs they have held as of the current date.?

Question

Which of the following best describes the data type and level of measurement for the variable being measured by this question?

1. numerical, continuous, ratio scale

2. numerical, discrete, ratio scale

3. numerical, continuous, interval scale

4. numerical, discrete, interval scale

my answer is # 2, but it could be # 4. thanks for checking my answer.

Answer 1

Uh . . . 7pi?

Answer 2

2. Numerical, discrete, ratio scale

It's a ratio scale because a ratio of 2 such variables is valid -- for example, 4 jobs *is* twice as many as 2, so a ratio of 4 jobs/2 jobs is valid.

There are very few things that are interval data -- the only common one (I can think of) is temperature on the fahrenheit or celsius scales. 100 degrees is not twice as much heat as 50 degrees, so ratios of temperature (using those scales) give nonsensical results. Ergo, kelvin.
