If a researcher collects data from 356 adolescents via surveys, the 356 individuals are a ______.

Explanation:
Understanding the difference between population and sample. The researcher is gathering data from a subset of the group of interest, so the 356 adolescents are a sample. The population would be all adolescents the study aims to describe. A parameter is a fixed value describing the population (for example, the true average age of all adolescents). A statistic is a value calculated from the sample (for example, the sample mean age). The data from these 356 individuals are used to estimate population characteristics, not to define the entire population itself. Therefore, the 356 individuals are a sample.
