the basic concepts in statistics. Chapter two is devoted for organizing and graphing data set, and Chapter three is about numerical descriptive measure. Chapter four is concerned with basic concepts of probability and counting rule, and Chapter five is about random variables and their probability distributions.
All of the major topics of an introductory level statistics course for social science are covered. Background areas include levels of measurement and research design basics. Descriptive statistics include all major measures of central tendency and dispersion/variation.
The Five Basic Words of Statistics. The five words population, sample, parameter, statistic (singular), and variable form the basic vocabulary of statistics. You cannot learn much about statis-tics unless you first learn the meanings of these five words.

INTRODUCTION TO STATISTICS Statistics is the branch of mathematics that deals with the techniques for collecting, analyzing, and drawing conclusions from data (Snedecor and Cochran, 1980). Statistics are the analytical backbone of science.
The text covers all material needed for an introduction and intermediate statistics course: starting with descriptive statistics, then the elements of probability theory needed for statistics, and finishing with a large portion dedicated to inferential statistics, where all topics of hypothesis testing and regression are covered.

Introduction. The purpose of this learning module is to introduce you to some of the fundamental definitions and techniques related to analyzing measurements with statistics. In all the definitions and examples discussed here, we consider a collection (sample) of measurements of a steady parameter.
This book covers the standard topics for an introductory statistics courses: basic terminology, a one-chapter introduction to probability, a one-chapter introduction to distributions, inference for numerical and categorical data, and a one-chapter introduction to linear regression.
Statistics is a branch of mathematics used to summarize, analyze, and interpret a group of numbers or observations. We begin by introducing two general types of statistics: • Descriptive statistics: statistics that summarize observations. • Inferential statistics: statistics used to interpret the meaning of descriptive statistics.
