A part of the population from which we actually collect information: used to draw conclusions about the entire population. Sampling design: describes exactly how to choose a sample from the population. All information needed to describe the parameters directly is provided: not practical. Statistical inference: meaningful conclusions about a population based on sample results o. Inferring things about population parameters based on sample statistics. Sample individual/unit variables data statistics statistical inference. Say exactly what population we want to describe. Say exactly what we want to measure (exact definitions of variables) A sample selected by taking the members of the population that are easiest to reach.
