Possible values are isolated points along a number line (e.g. shoe size, age in years) are described as

Explanation:
Discrete numerical data. When the possible values appear as separate, distinct points on the number line, you’re looking at discrete data. Shoe size and age in years fit this because you can only have specific sizes and whole-number ages, with gaps between them rather than a smooth continuum. Qualitative data are categories and not numeric, so that’s not the fit here. Continuous data would let you measure any value within a range, with no gaps, which isn’t the case for shoe size or age in years.
