You can compute the mean for a variable measured at what level?

Question

Quizplus · Accepted Answer

The mean can be computed for variables measured at the interval level because this level of measurement assumes equal distances between measurements, allowing for the calculation of an average. Nominal and qualitative data represent categories without a meaningful order or interval, making mean calculation inappropriate. Ordinal data, while ordered, does not assume equal intervals between ranks.
