paraphrase as for my favorite quantitative model, my favorite model is the sampling process. Sampling is the process of selecting a representative sample of elements from a specified population to estimate properties of that population. This includes finding that percentage or number with a specific opinion, using statistical methods. You can do this through random sampling which is making sure every member in the population has the same chance of being selected. Selecting elements without replacement needs to be done carefully because in this case, respondents are chosen based on their characteristics and once they are chosen they cannot be used again
