## Is IQ an interval or ratio?

## What level of measurement is grade level?

## What level of measurement is IQ level?

[Interval] An IQ score (or a standardized score on many other kinds of tests, such as achievement tests) is probably best considered as falling at an interval level of measurement. Some argue that such scores are at the ordinal level, providing only an ordering of performance.

## Is age an interval or ratio?

A great example of this is a variable like age. Age is, technically, continuous and ratio. A person’s age does, after all, have a meaningful zero point (birth) and is continuous if you measure it precisely enough. It is meaningful to say that someone (or something) is 7.28 year old.
