Question

Quizplus · Accepted Answer

The use of hammers to rate the difficulty of home improvement projects represents an ordinal scale, where the levels (3, 2, 1) have a natural order and indicate a higher or lower degree of difficulty. However, there is no true numerical relationship between the levels, as the difference between a 2 and a 1 may not necessarily be the same as the difference between a 3 and a 2. This means that an interval or ratio scale, where there are equal intervals between levels and a true zero point, would not be appropriate in this context. A nominal scale, where categories are named but there is no inherent order or ranking, would also not apply here.
