Final answer:
Q-1R is a quarterly periodicity code. The number of times per week is quantitative discrete data because it represents a countable number of events. Duration is quantitative continuous data as it can vary in continuous range and include decimals.
Step-by-step explanation:
The code Q-1R is an example of a quarterly periodicity code. This means that whatever is being referenced occurs once every quarter, or four times per year.
\\\\
Regarding the types of data, the number of times per week is quantitative discrete data because it represents a countable number of occurrences that can take on only integer values. For example, you can visit a park 3 times or 4 times, but not 3.5 times in a week.
\\\\
Duration (amount of time), on the other hand, is an example of quantitative continuous data because it can take on any value within a given range, including fractions or decimals. For instance, a visit to the park can last 1.5 hours or 2.25 hours.
