The MMT rating system is an example of which data type?

• A. Nominal data
• B. Ordinal data
• C. Interval data
• D. Ratio data

Answer: (B)

The main idea is that this rating system places muscle strength on a ranked scale, where higher numbers mean more strength, but the gaps between numbers aren’t assumed to be equal. That means you can tell which strength level is higher, but you can’t quantify exactly how much stronger one level is than the next. Ordinal data are data that are ordered: you know the sequence from low to high, but the differences between adjacent levels aren’t necessarily uniform. In contrast, nominal data have no inherent order (categories without ranking), interval data require equal intervals between values but have no true zero, and ratio data have equal intervals with a true zero. Since the MMT scale shows order without guaranteed equal spacing, it’s best described as ordinal data.
