Final answer:
The 'number of times per week' is quantitative discrete data because it involves a countable number of occurrences that cannot be fractional. This data type is numeric and must have integral values.
Step-by-step explanation:
The question 'Number of times per week is what type of data?' can be answered by identifying the nature of the data mentioned. The data in question pertains to the number of times something occurs within a set period, which is a week in this context.
Answer (b) quantitative discrete is the correct choice. This type of data is counted and cannot take on fractional values, as you cannot count something happening a fraction of a time. For example, you can have 3 or 4 visits to the gym per week, but not 3.5 times. In contrast, qualitative data refers to non-numeric information that describes categories or characteristics, and quantitative continuous data includes numeric values that can be measured on a continuous scale, such as height or temperature, which can take on any value within a range.
