Title: Using Probability in Search-and-Rescue Operations | Prediction by the Numbers
URL: https://aptv.pbslearningmedia.org/resource/nvpn-sci-sarops/using-probability-in-search-and-rescue-operations-prediction-by-the-numbers/
Description:

Explore how probability can be used to help find people lost at sea, even when rescuers have very little information, in this video from NOVA: Prediction by the Numbers. To improve its search-and-rescue efforts, the U.S. Coast Guard has developed a system that uses Bayesian inference, a mathematical concept that dates back to the 18th century. The Search and Rescue Optimal Planning System (SAROPS) uses a mathematical approach to calculate probabilities of where a floating person or object might be based on changing ocean currents, wind direction, or other new information. Use this resource to stimulate thinking and questions about appropriate uses of statistical methods.

Title: P-Value as a Benchmark in Experimental Research | Prediction by the Numbers
URL: https://aptv.pbslearningmedia.org/resource/nvpn-sci-pvalue/p-value-as-a-benchmark-in-experimental-research-prediction-by-the-numbers/
Description:

Learn about the origins and meaning of “p-value,” a statistical measure of the probability that has become a benchmark for success in experimental science, in this video from NOVA: Prediction by the Numbers. In the 1920s and 1930s, British scientist Ronald A. Fisher laid out guidelines for designing experiments using statistics and probability to judge results. He proposed that if experimental results were due to chance alone, they would occur less than 5 percent (0.05) of the time. The lower the p-value, the less likely the experimental results were caused by chance. Use this resource to stimulate thinking and questions about the use of statistics and probability to test hypotheses and evaluate experimental results.

Title: Algebra II Module 4, Topic A: Probability
URL: https://www.engageny.org/resource/algebra-ii-module-4-topic-a-overview
Description:

In Module 4, Topic A chance experiments, sample space, and events such as unions, intersections, and complements are explained. Probabilities of unions and intersections are calculated using data in two-way tables and Venn diagrams are used to represent a sample space and reinforce the probability formulas. Conditional probability is also introduced.
