Question

lee has earned an undergraduate degree in biology. he is motivated to become a doctor. he has ascertained three letters of recommendation from his professors and has applied to medical school. he has not yet proposed to his girlfriend. which of these characteristics referring to lee is a continuous variable?

1. his college degree
2. his school application
3. his letters of support
4. his motivation

Explanation:

To determine a continuous variable, we analyze each option:

• "His college degree" is a categorical variable (e.g., biology degree, other degrees), not continuous.
• "His school application" is a binary or categorical concept (applied or not), not continuous.
• "His letters of support" is a discrete variable (countable, like 3 letters, can only take whole number values).
• "His motivation" can take on any value within a range (e.g., low, medium, high, or measured on a scale with infinite possible values between extremes), so it is a continuous variable.

Answer:

1. his motivation
