Verified step by step guidance

1. Understand the difference between quantitative and qualitative data. Quantitative data represents numerical values that can be measured or counted, while qualitative data represents categories or labels without inherent numerical meaning.
2. Review each option and determine whether it represents numerical measurements or categorical labels.
3. The brands of smartphones owned by employees are categories (qualitative data), as they describe types without numerical values.
4. The heights of students in centimeters are numerical measurements (quantitative data), as height is a measurable quantity expressed in numbers.
5. The colors of cars and types of cuisine are also categories (qualitative data), describing attributes without numerical values.
