Studdy Solution

STEP 1

1. A person's favorite color is inherently a qualitative attribute because it describes a characteristic that cannot be measured numerically.
2. The term "quantitative variable" refers to variables that can be measured and expressed numerically, allowing mathematical operations to be performed on them.
3. The term "categorical variable" refers to variables that represent categories or groups and are usually described by names or labels, rather than numbers.

STEP 2

1. Define and differentiate between categorical and quantitative variables.
2. Classify a person's favorite color based on the definitions provided.

STEP 3

Define a categorical variable.
A categorical variable is a type of variable that takes on values that are names or labels. These values represent different categories or groups. Examples include colors, types of food, or brands of cars.

STEP 4

Define a quantitative variable.
A quantitative variable is a type of variable that can be measured numerically. These values represent quantities and can be subjected to mathematical operations. Examples include height, weight, or age.

STEP 5

Determine the nature of a person's favorite color.
A person's favorite color is an example of a categorical variable because it describes a characteristic that can be grouped into different categories (e.g., red, blue, green) without involving any numerical measurement.

STEP 6

Classify a person's favorite color as a categorical variable.
Based on the definitions and the nature of the variable, a person's favorite color is classified as a categorical variable.
