PG STAT 531 Lecture 2 Descriptive statistics

This document provides an overview of descriptive statistics. It discusses that descriptive statistics are used to describe basic features of data through simple summaries, without drawing inferences. The document outlines various measures of central tendency like mean, median and mode. It also discusses measures of dispersion such as range, variance and standard deviation that describe how spread out the data is. The key purpose of descriptive statistics is to present quantitative data in a simplified and manageable form.
