There is a growing movement to introduce elements of statistics and probability into the secondary and even the elementary school curriculum, as part of basic literacy in mathematics.

Although many articles in the education literature recommend how to teach statistics better, there is little published research on how students actually learn statistics concepts. View PDF. Save to Library. Create Alert. Launch Research Feed.

Probability and Statistics

Randomness is all around us. Probability theory is the mathematical framework that allows us to analyze chance events in a logically sound manner. The probability of an event is a number indicating how likely that event will occur. This number is always between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. A classic example of a probabilistic experiment is a fair coin toss, in which the two possible outcomes are heads or tails. For an unfair or weighted coin, the two outcomes are not equally likely. You can change the weight or distribution of the coin by dragging the true probability bars on the right in blue up or down.

Basic Probability

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. A simple example is the tossing of a fair unbiased coin. These concepts have been given an axiomatic mathematical formalization in probability theory , which is used widely in areas of study such as statistics , mathematics , science , finance , gambling , artificial intelligence , machine learning , computer science , game theory , and philosophy to, for example, draw inferences about the expected frequency of events. Probability theory is also used to describe the underlying mechanics and regularities of complex systems.

These are notes based on the book by Dorrie2 which we highly recommend for those more interested in the area. Many of the exercises given in the lecture notes are based on the text.

Conditional Probability

Suppose a polling organization questions 1, voters in order to estimate the proportion of all voters who favor a particular bond issue. We would expect the proportion of the 1, voters in the survey who are in favor to be close to the proportion of all voters who are in favor, but this need not be true. There is a degree of randomness associated with the survey result. If the survey result is highly likely to be close to the true proportion, then we have confidence in the survey result. If it is not particularly likely to be close to the population proportion, then we would perhaps not take the survey result too seriously. The likelihood that the survey proportion is close to the population proportion determines our confidence in the survey result. For that reason, we would like to be able to compute that likelihood.

This book sets out basic statistical tools as they have been applied in actual legal disputes.

The axioms of probability and the fundamental rules are explained with the help of Venn diagrams. Later, the concepts of univariate and bivariate random variables along with their respective forms of probability distribution function, cumulative distribution function, and joint probability distribution are discussed.

This book offers an introduction to concepts of probability theory, probability distributions relevant in the applied sciences, as well as basics of sampling distributions, estimation and hypothesis testing.
