# Are these two datasets interval?

I have two dataset: population density and case fatality rate. Population density is measured as number of people living in an area divided by that area size in square miles (number of people/area size). Case fatality rate is calculated as total death from an infection divided by total number of infections (total death/total infection). Are population density and case fatality rate intervals?

• Presumably you mean of "interval data type." But could you explain why the answer would be relevant to any kind of data analysis or investigation?

• Both datasets take only non-negative values. Jan 10, 2022 at 22:33
• @whuber yes I meant are they interval data type. I want to find if there is a correlation between them. I use population density as the independent value.

• @BruceET yes. So are they interval data type?

• For assessing relationships or correlations, it is superfluous to determine the data type.
