Why does fitting a model to data not guarantee a perfect representation of the true relationship?

ABecause fitting changes the data points to new values

BBecause fitting always finds the exact true relationship

CBecause data may have noise, model assumptions may be wrong, or data may be incomplete

DBecause fitting ignores the data and uses random values

Step-by-Step Solution

Solution:

Step 1: Recognize data and model limitations
Real data often contains noise and models have assumptions that may not fully match reality.
Step 2: Understand fitting limitations
Fitting finds the best approximation but cannot perfectly capture the true relationship if data or model is imperfect.
Final Answer:
Because data may have noise, model assumptions may be wrong, or data may be incomplete -> Option C
Quick Check:
Fitting approximates, not guarantees perfect fit = C [OK]

Quick Trick: Fitting approximates relationships, not perfect matches [OK]
