Verified step by step guidance

1. Understand the definition of quantitative data: Quantitative data is numerical and can be measured or counted. It often involves quantities and can be used for mathematical calculations.
2. Examine each option to determine if it is numerical: The amount of hours students study per week is numerical, as it can be measured in hours. The heights of basketball players are also numerical, measured in centimeters. The outcomes of ten rolls of a die are numerical, as they result in numbers from 1 to 6.
3. Identify the option that is not numerical: The brands of smartphones owned by students are not numerical. They are categorical, as they describe categories or groups (e.g., Apple, Samsung, etc.) rather than quantities.
4. Recognize that categorical data is not quantitative: Categorical data, like the brands of smartphones, is qualitative and describes characteristics or qualities rather than quantities.
5. Conclude that the brands of smartphones owned by students is the option that is NOT quantitative data, as it does not involve numerical measurement or counting.
