Statistics Ch 1: The Nature of Statistics Notes 1.1 Statistic Basics Population vs Sample Population A collection of all items or individuals, being studied. In other words whole. Sample A group taken out of the population, or in other words a part of the population, which is meant to resemble the whole. Through this, information is obtained. e.g. A researcher could hope to figure out the amount of time college students in Mississippi study. The population would be college students of Mississippi, but it would be harder to ask every college student about their study time. To save time, the researcher might take a sample from Mississippi State, using the school as
