NUMB3RS - Season 3 - "Contenders" - Choosing Contenders
...e skill levels and past performances of each fighter. They find that one fighter has had an easy path to the championship because this fighter is always up against opponents who are weaker than he is. Students use two 'rankings' to determine a rating for each team in the NFC of the NFL in the 20...https://education.ti.com/en/activity/detail/numb3rs--season-3--contenders--choosing-contenders
Testing Goodness-of-Fit and Two-Way Table Chi-Square
Students perform chi-square tests to see if data follows a hypothesized distribution. They also study the two-way table analysis.https://education.ti.com/en/activity/detail/testing-goodnessoffit-and-twoway-table-chisquare
Collecting Data
In this activity, students investigate how to use random numbers to collect samples and how to randomly assign subjects to experiments to collect data. They also use the CBL system to collect data in real time.https://education.ti.com/en/activity/detail/collecting-data
Density Curves
Students will be introduced to density curves as a simple analysis of a data set. They also will investigate where the median and mean lie on symmetric or skewed graphs.https://education.ti.com/en/activity/detail/density-curves
Data Analysis: Home Runs in Major League Baseball

NUMB3RS - Season 2 - "Mind Games" - Right or Wrong
In "Mind Games," a psychic shocks Charlie by incorrectly guessing the color (black or red) of 25 cards in a row. As Larry says, "the probability of getting them all wrong is the same as getting them all right." This activity applies the binomial theorem to the probability of correctly guessing a ...https://education.ti.com/en/activity/detail/numb3rs--season-2--mind-games--right-or-wrong
