Answer: (D)

Verified step by step guidance

1. Understand the meaning of each term: Estimation refers to approximating a value based on data; Sampling is the process of selecting a subset from a population; Classification involves grouping data into categories; Quantification means expressing observations as numerical values.
2. Recognize that when using a graphing calculator to analyze data, you are converting observed information into numbers to work with mathematically.
3. Identify that this process of converting observations into numbers aligns with the definition of quantification.
4. Confirm that the other options (estimation, sampling, classification) do not specifically describe the act of expressing observations as numbers.
5. Conclude that the best term to describe this process is quantification.
