Question

Quizplus · Accepted Answer

The mean can be calculated for ratio, interval, and even ordinal data under certain conditions, though it's most meaningful for ratio and interval data. Ratio and interval data are quantitative, allowing for arithmetic operations required to calculate the mean. Ordinal data, while not typically used for mean calculations due to its categorical nature, can in some contexts be treated numerically, especially if the ordinal categories have a consistent scale. However, it's most common and appropriate to calculate means for ratio and interval data due to their inherent numerical properties.
