A data set consists of a set of numerical values. Which, if any, of the following statements could be correct?

There is no mode.
There are two modes.
There are three modes.

Depending on the underlying data, all three could be correct. The first would have equal number of scores in all categories. The second would tend to have two underlying groups, like hand-grip strength of men and women. The third might also include grade school children.

I hope this helps.
