As we near the end of the series, we're going look at how statistics impacts our lives. Today, we're going to discuss how statistics is often used and misused in the courtroom. We're going to focus on three stories in which three huge statistical errors were made: the handwriting analysis of French officer Alfred Dreyfus in 1894, the murder charges of mother Sally Clark in 1998, and the expulsion of student Jonathan Dorfman from UC San Diego in 2011.
La statistique est la branche des mathématiques qui consiste à recueillir des données, puis à les analyser afin d'établir des hypothèses utilisées pour prédire des évènements.
Les statistiques sont les données recueillies et celles obtenues à partir de calculs.
Students learn that math is important in navigation and engineering. They learn about triangles and how they can help determine distances. Ancient land and sea navigators started with the most basic of navigation equations (speed x time = distance). Today, navigational satellites use equations that take into account the relative effects of space and time. However, even these high-tech wonders cannot be built without pure and simple math concepts â basic geometry and trigonometry â that have been used for thousands of years.
Lesson for PE 30 examining the difference between Steady State Exercise and High Intensity Interval Training.
Steller Sea Lions are charismatic marine mammals who have captured the hearts of many by their curious nature and powerful roar. These top predators help to maintain balance in the ecosystem. Their health and stability help indicate to us the health of the ocean as a whole. Explore this interactive activity to learn about Steller Sea Lions, their pinniped cousins, and how our simple choices have a powerful impact on the health and wellbeing of these incredible animals.

I decided to do this activity as a fun way to get my students engaged in the ever daunting physics unit in science 10. This activity was very easy to set up and I already had access to most of the materials at school. The basic idea of this was to create a launcher or sling shot with the materials you are given that will launch your army man the farthest. I gave each group 3 tries as sometime the launch didn’t go as planned. We marked the farthest launch and I had a prize for the winning group.
