Math Problem Statement
Solution
The image asks to classify variables as either quantitative or categorical. Here’s the solution for each variable:
-
(a) Eye color of a favorite singer:
- Type of variable: Categorical
Explanation: Eye color is a quality or attribute (e.g., blue, green, brown), so it’s categorical.
- Type of variable: Categorical
-
(b) Price (in dollars) of a shirt on the clearance rack:
- Type of variable: Quantitative
Explanation: Price is a measurable number, so it’s quantitative.
- Type of variable: Quantitative
-
(c) Amount (in pounds) of weight needed to break a bridge cable:
- Type of variable: Quantitative
Explanation: Weight is a measurable number, so it’s quantitative.
- Type of variable: Quantitative
-
(d) University in which a student is enrolled:
- Type of variable: Categorical
Explanation: The name of the university is a category (e.g., Harvard, Stanford), so it’s categorical.
- Type of variable: Categorical
Would you like further clarification or additional examples?
Here are 5 related questions to expand your understanding:
- What are the key differences between categorical and quantitative variables?
- Can some variables belong to both types? Why or why not?
- How do you treat categorical variables in statistical analysis?
- What are some common visualizations for categorical data?
- Why are quantitative variables better suited for mathematical computations?
Tip: Categorical variables often represent groups or labels, while quantitative variables always involve numbers that can be meaningfully compared or calculated.
