Verified step by step guidance

1. Understand the difference between qualitative and quantitative data. Quantitative data represents numerical values that can be measured or counted, while qualitative data represents categories or characteristics that cannot be measured numerically.
2. Review each option to determine if it represents quantitative data:
3. - 'The types of cuisine served at local restaurants' is categorical data (qualitative) because it describes categories of cuisine, not numerical measurements.
4. - 'The brands of smartphones owned by survey participants' is also categorical data (qualitative) because it identifies categories (brands) rather than numerical values.
5. - 'The heights of students in a classroom measured in centimeters' is numerical data (quantitative) because height is a measurable quantity expressed in numbers.
