• ### Probability and Statistics in Aerospace Engineering

This resource was prepared to give the practicing engineer a clear understanding of probability and statistics with special consideration to problems frequently encountered in aerospace engineering. It is conceived to be both a desktop reference and a refresher for aerospace engineers in government and industry. It could also be used as a supplement to standard texts for in-house training courses on the subject.

• ### Introduction to Statistics (NASA Lesson)

These pages explain the following basic statistics concepts: mean, median, mode, variance, standard deviation and correlation coefficient (with example from the Institute on Climate and Planets).

• ### Using Computers for Statistical Analysis (NASA Activity)

This lesson introduces students to creating spreadsheets for statistical analysis.

• ### Team Extreme: The Statistics of Success (NASA Activity)

This program focuses on the teamwork required to produce a successful mission and the importance of statistics in project design and management. Using the video and a hands-on lesson, students learn about statistical analysis and how people use statistics, such as mean, median, mode and range, to make decisions. Members of the Penske Racing Team and engineers from Pratt & Whitney Rocketdyne help students investigate the relationship between work, energy and power as they look at race car design, the space shuttle and the International Space Station.

• ### Collection: Calculators

Our online calculators and converters can help you in many daily tasks that require calculations to complete.

• ### Collection: Statistical Calculators

Free statistical calculators online.  Our basic statistical calculators will help you in common tasks you might encounter and deal mostly with simple distributions.

• ### Analysis Tool: Kappa as a Measure of Concordance in Categorical Sorting

Calculates unweighted kappa and kappa with linear and quadratic weightings, along with some other measures of concordance.

• ### Analysis Tool: One-Way Analysis of Variance for Independent or Correlated Samples

This page will compute the One-Way ANOVA for up to five samples. The design can be either for independent samples or correlated samples (repeated measures or randomized blocks). This page will also perform pair-wise comparisons of sample means via the Tukey HSD test

• ### Analysis Tool: Two-Factor ANOVA with Repeated Measures on Both Factors

This page will perform a two-way factorial analysis of variance for designs in which there are 2-4 levels of each of two variables, A and B, with each subject measured under each of the AxB combinations.

• ### Analysis Tool: Two-Way Analysis of Variance for Independent Samples

This page will compute the Two-Way Factorial ANOVA for Independent Samples, for up to four rows by four columns. This page will also calculate the critical values of Tukey's HSD for purposes of post-ANOVA comparisons.
