Calculates the z-ratio and associated one-tail and two-tail probabilities for the difference between two correlated proportions, such as might be found in the case where the proportions are based on the same sample of subjects or on matched samples.
Calculates the z-ratio and associated one-tail and two-tail probabilities for the difference between two correlated proportions, such as might be found in the case where the proportions are based on the same sample of subjects or on matched samples.
This page will perform a t-test for the significance of the difference between the observed mean of a sample and a hypothetical mean of the population from which the sample is randomly drawn. The user will be asked to specify the sample size as the page opens.
The Student Dust Counter is an instrument aboard the NASA New Horizons mission to Pluto, launched in 2006. As it travels to Pluto and beyond, SDC will provide information on the dust that strikes the spacecraft during its 14-year journey across the solar system. These observations will advance our understanding of the origin and evolution of our own solar system, as well as help scientists study planet formation in dust disks around other stars.
In this lesson, students explore the SDC data interface to establish any trends in the dust distribution in the solar system. Students record the number of dust particles, "hits," recorded by the instrument and the average mass of the particles in a given region.
The Neutral Buoyancy Laboratory allows astronauts an atmosphere resembling zero gravity (weightlessness) in order to train for missions involving spacewalks. In this activity, students will evaluate pressures experienced by astronauts and scuba divers who assist them while training in the NBL. This lesson addresses correlation, regression, residuals, inerpreting graphs, and making predictions.
NASA's Math and Science @ Work project provides challenging supplemental problems for students in advanced science, technology, engineering and mathematics, or STEM classes including Physics, Calculus, Biology, Chemistry and Statistics, along with problems for advanced courses in U.S. History and Human Geography.
Math and Science @ Work presents an activity for high school AP Statistics students. In this activity, students will look at data from an uncalibrated radar and a calibrated radar and determine how statistically significant the error is between the two different data sets.

NASA's Math and Science @ Work presents an activity focused on correlation coefficients, weighted averages and least squares. Students will analyze the data collected from a NASA experiment, use different approaches to estimate the metabolic rates of astronauts, and compare their own estimates to NASA's estimates.

A song to teach about Benford's Law for the probability distribution of first digits in real data. The lyrics are copyright by Lawrence Mark Lesser as a parody of Harry Nilsson's "One" made popular in 1969 by "Three Dog Night". "One is the Likeliest Number" was first published in the Spring 2011 issue of "Teaching Statistics". Free for use in non-profit education settings. Musical accompaniment realization and vocals are by Joshua Lintz from University of Texas at El Paso.
A song to help students confront the "equiprobability bias". Lyrics and music were written by Lawrence Mark Lesser of University of Texas at El Paso. The song won an honorable mention in the 2013 CAUSE A-Mu-sing competition. Free for use in non-profit education settings.
A song for teaching about the importance of penalized regression methods (ridge regression, LASSO, etc...). The song was written by Bradley Turnbull, Joe Usset, Sidd Roy, and Kyle White who, along with Kristin Linn and Jason Osborne, form the North Carolina State University Statistics Department Graduate Student band, "The Fifth Moment". The lyrics may be sung to the tune of the 2008 hit "Shake It" by the American pop group "Metro Station". "Shrink It" also won an honorable mention in the 2013 CAUSE A-Mu-sing competition. Available for free use in non-profit education settings.
A song to aid in teaching upper division or masters level regression concepts. The lyrics were written by Kyle White from North Carolina State University for performance by the NCSU band "The Fifth Moment" (Kristin Linn, Jason Osborne, Siddharth Roy, Bradley Turnbull, Joseph Usset, and Kyle White). The song is a parody of the 2001 hit "The Middle" by the American alternative rock band Jimmy Eat World. The song won an honorable mention in the 2013 CAUSE A-Mu-sing competition and a performance of it by "The Fifth Moment" can be seen at http://www.youtube.com/watch?v=zdhqQGrCITI Free for use in non-profit education settings.
