Once a statistical experiment yields results, these results have to be qualified. Battery makers only test a sample of their product to estimate how long each battery will last. Confidence intervals are introduced to determine how accurate that estimate is. Does coaching for the Scholastic Aptitude Test make a difference? Significance tests determine whether a correlation between variables is meaningful, or just occurred by chance.
This series of DVDs contains segments on a variety of topics in beginning statistics and is ideal for high school and undergraduate students who are in need of clear explanations of ideas in chance and data. Each DVD contains short (generally 12-15 minute) segments on specific topics in beginning statistics, mostly extracted from the Against All Odds series (seen on ABC TV's Open Learning program). The snippets are short enough to encourage repeated viewing and consolidation of new learning, and easily fit into any lesson structure and length.
