Verified step by step guidance

1. Understand the difference between qualitative and quantitative data. Qualitative data describes categories or qualities, such as brands, types, or colors, which cannot be measured numerically.
2. Quantitative data, on the other hand, consists of numerical values that represent measurable quantities, such as height, weight, or age.
3. Review each option and determine if it represents a measurable quantity or a category. For example, 'brands of smartphones' and 'types of cuisine' are categories, so they are qualitative data.
4. Recognize that 'heights of students measured in centimeters' is a numerical measurement, making it quantitative data.
5. Conclude that the example of quantitative data is the one involving heights, as it involves numerical values that can be measured and analyzed mathematically.
