A song that may be used in discussing the definition and interpretation of the P-Value in significance testing. The lyrics were written by Mary McLellan from Aledo High School in Aledo, Texas as one of several dozen songs created for her AP statistics course. The song may be sung to the tune of Van Morrison’s 1967 classic rock song BlBrown Eyed Girl. Also, an accompanying video may be found at https://www.youtube.com/watch?v=TmQvXhN7Exc statistical topic: Significance Testing Principles – P-value

This page will perform basic multiple regression analysis for the case where there are several independent predictor variables, X1, X2, etc., and one dependent or criterion variable, Y. Requires import of data from a spreadsheet.

This activity focuses on basic ideas of linear regression. It covers creating scatterplots from data, describing the association between two variables, and correlation as a measure of linear association. After this activity students will have the knowledge to create output that yields R-square, the slope and intercept, as well as their interpretations. This activity also covers some of the basics about residual analysis and the fit of the linear regression model in certain settings. The corresponding data set for this activity, 'BAC data', can be found at the following web address: http://www.causeweb.org/repository/ACT/BAC.txt

This activity explains the important features of a distribution: shape, center, spread, and unusual features. It also covers how to determine the difference between mean and median, and their respective measures of spread, as well as when to apply them to a particular distribution. Graphical displays such as: histograms and boxplots are also introduced in this activity. The corresponding data set for this activity is found at the following web address: http://www.causeweb.org/repository/ACT/food.txt

This activity enables students to learn about confidence intervals and hypothesis tests for a population mean. It focuses on the t-distribution, the assumptions for using it, and graphical displays. The activity also focuses on how to interpretations a confidence interval, a p-value, and a hypothesis test.

Song addresses the value of a scientific poll. May be sung to the tune of the Rolling Stones' hit "It's Only Rock 'N Roll (But I Like It)" by Mick Jagger and Keith Richards. Musical accompaniment realizationare by Joshua Lintz and vocals are by Mariana Sandoval from University of Texas at El Paso.

A joke about the over-use of playing card examples in teaching probability.

That was why statistics had to be invented - because people were so unstable and irrational, taken one at a time. A quote of American science fiction author Raymond F. Jones (1915 - 1994) found in his 1956 short story "The Non-Statistical Man". The quote also appears in "Statistically Speaking: A dictionary of quotations" compiled by Carl Gaither and Alma Cavazos-Gaither.

... we must remember that measures were made for man and not man for measures. a quote of popular science and science fiction author Isaac Asimov (1920 - 1992) in "Of Time and Space and Other Things" page 143, Avon Books, 1965. The quote also appears in "Statistically Speaking: A dictionary of quotations" compiled by Carl Gaither and Alma Cavazos-Gaither.

Chance is only the measure of our ignorance. A quote from French mathematician and physicist Jules Henri Poincare (1854 - 1912) found in "The Foundations of Science", page 395, The Science Press, 1913. The quote also appears in "Statistically Speaking: A dictionary of quotations" compiled by Carl Gaither and Alma Cavazos-Gaither.
