NUMB3RS - Season 3 - "Democracy" - No Desk Left Behind
In "Democracy", Charlie calculates the likelihood that five people who knew each other would have died by accident in a two-week period. He estimates that the odds of this are 700 million to 1. To estimate likelihood of an event, a simulation can be used. In this activity, students use a simulati...https://education.ti.com/en/activity/detail/numb3rs--season-3--democracy--no-desk-left-behind

What's Normal, Anyway?
Students explore normal distribution and several properties. First, simulate a binomial experiment and use a histogram of the data to examine the general shape of a normal curve. They graph a normal distribution given the mean and standard deviation. They see how the graph changes when just the m...https://education.ti.com/en/activity/detail/whats-normal-anyway_1
NUMB3RS - Season 3 - "Contenders" - Dialing Ben
In "Contenders," David's friend, Ben Ellis, is a suspect of two murders. The FBI can not find Ben when he stops using his cell phone. Charlie explains that Ben may be using a friend's cell phone and might be identified by his unique calling pattern, so he compares the cell phone records of Ben an...https://education.ti.com/en/activity/detail/numb3rs--season-3--contenders--dialing-ben

What Is Your Grade (Part 1)
In this activity, students will use the CellSheet Application and set up a spreadsheet. They will determine the mean of a set of values and find a minimum value to be added to a set of values to obtain a given mean.https://education.ti.com/en/activity/detail/what-is-your-grade-part-1
Testing Hypotheses (Means, Proportions, and Standard Deviations)
In this activity, students evaluate hypotheses.https://education.ti.com/en/activity/detail/testing-hypotheses-means-proportions-and-standard-deviations
NUMB3RS - Season 2 - "Toxin" - How Hard Can It Be?
In "Toxin," the FBI tracks a serial poisoner who uses contaminated drugs. In this activity, the FBI intercepted an encrypted message they believe contains a phone number that could lead to an "insider" who may be helping the poisoner. Don suggests using a computer to start trying to break the cod...https://education.ti.com/en/activity/detail/numb3rs--season-2--toxin--how-hard-can-it-be
NUMB3RS - Season 2 - "The Running Man" - The Eyes Have It
The FBI is investigating a robbery at the research facility of a large company. The FBI believes that the robbers were employees of the company, because they were able to bypass the iris recognition security scan and gain entrance. However, a security camera was able to capture a partial image of...https://education.ti.com/en/activity/detail/numb3rs--season-2--the-running-man--the-eyes-have-it
What is A Kanban?
In this activity, students use the CellSheet™ Application to understand how to track inventory and predict future trends based on average daily use. They will collect data, analyze it and make predictions. They also learn to use linear regression model to predict future trends.https://education.ti.com/en/activity/detail/what-is-a-kanban
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
What! A Mistake!
Students learn about Type I and Type II errors. Then, for a given scenario, they calculate the probabilities of errors and the power of the test.https://education.ti.com/en/activity/detail/what-a-mistake
Testing Claims About Proportions
Students find z-scores and critical values to test claims about proportions.https://education.ti.com/en/activity/detail/testing-claims-about-proportions
NUMB3RS - Season 2 - "The O.G." - Is It Really Rare?
Suppose that historically, a shooting has occurred in Los Angeles an average of once every 6 hours. Suppose that Charlie is interested in the probability of 2 shootings occurring in a given 24-hour period. He could use a Poisson distribution to find that probability.https://education.ti.com/en/activity/detail/numb3rs--season-2--the-o-g---is-it-really-rare
Claims About Two Proportions
Students test claims about two proportions by calculating test statistics, critical values, and P-values, for both one-tailed and two-tailed tests.https://education.ti.com/en/activity/detail/claims-about-two-proportions_1
NUMB3RS - Season 2 - "Soft Target" - Are You Sure?
In "Soft Target," Charlie uses Linear Discriminant Analysis (LDA), a multiple regression method, to predict the next terrorist attack. This method, like many others used to predict events, may use a tree diagram to visualize possibilities. The use of tree diagrams is seen in probability.https://education.ti.com/en/activity/detail/numb3rs--season-2--soft-target--are-you-sure
Survey Project
Students survey other students (numerical and non numerical data) and calculate measures of central tendency (if possible) of data and make regular box-an-whisker plots and outlier box-and-whisker plots to analyze the data.https://education.ti.com/en/activity/detail/survey-project
