The most common parameters of a univariate statistical population are: Michael Akritas Lecture 3 Chapter 1: Basic Statistical Concepts Outline Proportions, Averages and Variances Statistical Experiments and Observational Studies The Role of Probability Approaches to Statistical Inference The key parameters of a population Proportions: Population- and Sample- Averages: Population- and Sample- Variance: Population- and Sample- Investigators are typically interested in learning about certain quantifiable aspects, or parameters as we called them, of the statistical population under investigation.
