1. The problem asks for the term that refers to the process of choosing a representative part of a population. 2. In statistics, when we want to study a large population, we often select a smaller group that represents the whole. This smaller group is called a sample. 3. The process of selecting this sample from the population is known as the **sampling technique**. 4. Other options like tabulation (organizing data), summation (adding numbers), and Sloven's formula (a formula for sample size determination) are related concepts but do not specifically mean choosing a representative part. 5. Therefore, the correct term is **sampling technique**.
