Math Problem Statement
assign each one with Categorical, discrete numerical, continuous numerical
Solution
The image shows a table where you need to classify variables into categorical, discrete numerical, or continuous numerical.
Here is how you can classify them:
-
How do you describe reasons for owning this material?
- Categorical (because it involves different qualitative reasons, such as 'For learning', 'For collection', etc.)
-
How many material items you owned that you would never discard/give away?
- Discrete Numerical (because it counts individual items, which are whole numbers)
-
How many hours of long-term material-use would you experience in the next week?
- Continuous Numerical (because time can be measured in fractions and not just whole numbers)
-
How often do you borrow materials instead of purchasing them yourself?
- Categorical (likely asks for responses such as 'Often', 'Sometimes', 'Rarely', which are categories)
Would you like more details on the classification criteria?
Here are 5 related questions:
- Can you think of other examples of discrete numerical data?
- Why is it important to differentiate between discrete and continuous numerical data?
- What are some typical uses of categorical data in real-world research?
- Can continuous data sometimes be presented in a discrete way? If so, how?
- How would you represent categorical data graphically?
Tip: In statistical analysis, continuous numerical data is often handled using different techniques than categorical or discrete numerical data.
