Overview[ edit ] In applying statistics to a problem, it is common practice to start with a population or process to be studied. Populations can be diverse topics such as "all persons living in a country" or "every atom composing a crystal". Ideally, statisticians compile data about the entire population an operation called census. This may be organized by governmental statistical institutes. The analysis of events governed by probability is called statistics. There are several competing interpretations of the actual "meaning" of probabilities. Frequentists view probability simply as a measure of the frequency of outcomes the more conventional interpretationwhile Bayesians treat probability more subjectively as a statistical procedure that endeavors to estimate parameters of an underlying distribution based on the observed distribution.

A properly normalized function that assigns a probability "density" to each possible outcome within some interval is called a probability density function or probability distribution functionand its cumulative value integral for a continuous distribution or sum for a discrete distribution is called a distribution function or cumulative distribution function.

A variate is defined as the set of all random variables that obey a given probabilistic law. It is common practice to denote a variate with a capital letter most commonly. The set of all values that can take is then called the rangedenoted Evans et al. Specific elements in the range of are called quantiles and denotedand the probability that a variate assumes the element is denoted.

Probabilities are defined to obey certain assumptions, called the probability axioms. Let a sample space contain the union of all possible events.Put statistical theories into practice with PROBABILITY AND STATISTICS FOR ENGINEERING AND THE SCIENCES, 9th Edition.

Always a favorite with statistics students, this calculus-based text offers a comprehensive introduction to probability and statistics while demonstrating how professionals apply concepts, models, and methodologies in today's engineering and scientific careers. Great textbook for the intro to statistics with mathematical background.

Covers a lot of material with reasonable depth. Some of the intro paragraphs to the chapters/sections might seem vague at first, as the authors intended it to be an "interesting example". Statistics is a branch of mathematics dealing with data collection, organization, analysis, interpretation and presentation.
