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
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
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
NUMB3RS - Season 2 - "Rampage" - I...It...Itera...Iteration
In "Rampage," a suspect enters the FBI Bullpen and moves about, apparently shooting people at random. Charlie examines a diagram of the killer's path through the Bullpen and suggests it might resemble Brownian motion. In this activity, students first model this motion with ten iterations by hand...https://education.ti.com/en/activity/detail/numb3rs--season-2--rampage--i---it---itera---iteration
NUMB3RS - Season 2 - "Mind Games" - Walkabout
In "Mind Games," Charlie uses the Fokker-Planck equation to predict the movement of illegal immigrants. The equation is used to predict the likely movement of something under the influence of external forces. It was originally developed to study Brownian motion, the apparently random movement of ...https://education.ti.com/en/activity/detail/numb3rs--season-2--mind-games--walkabout
NUMB3RS - Season 2 - "Mind Games" - Thumbs Up!
In "Mind Games," the FBI hires a psychic to help them solve a series of murders. To test how good he is, they show him the backs of a set of 25 playing cards and ask him to predict whether each is red or black. He gets every single one wrong. In this activity, students conduct an experiment and ...https://education.ti.com/en/activity/detail/numb3rs--season-2--mind-games--thumbs-up
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
NUMB3RS - Season 2 - "Judgement Call" - Filtering Suspects
In "Judgement Call,"Charlie helps the FBI sort through their case files for relevant suspects. He applies a logical filter to find the files most relevant to a specific crime. This activity explores Bayesian Filtering and exposes students to how math can be seen in the world around them.https://education.ti.com/en/activity/detail/numb3rs--season-2--judgement-call--filtering-suspects
NUMB3RS - Season 2 - "Harvest" - Markov Chain Links
In "Harvest," Charlie is trying to identify possible destinations and unrecorded routes of an ambulance driver suspected of transporting stolen organs. Charlie tells Colby that they can use a Hidden Markov Model to help narrow down these possibilities.https://education.ti.com/en/activity/detail/numb3rs--season-2--harvest--markov-chain-links
NUMB3RS - Season 2 - "Double Down" - That's So Random
In "Double Down," three college students attempt to get an edge in a casino card game by analyzing the mechanical randomization process used to shuffle the cards. As Charlie explains, the auto-shuffler relies on an algorithm to deal the cards in random order. The students are able to crack the al...https://education.ti.com/en/activity/detail/numb3rs--season-2--double-down--thats-so-random
NUMB3RS - Season 2 - "Soft Target" - Is This Seat Taken?
In "Soft Target," Alan is considering how to arrange people in seats at a wedding. Charlie points out that although there are many possibilities for seating arrangements, you reduce those possibilities if you decide who needs to sit next to whom.https://education.ti.com/en/activity/detail/numb3rs--season-2--soft-target--is-this-seat-taken
NUMB3RS - Season 3 - "Traffic" - Birthday Surprise
Students will study the birthday problem and other similar applications.https://education.ti.com/en/activity/detail/numb3rs--season-3--traffic--birthday-surprise
NUMB3RS - Season 3 - "Finders Keepers" - Barging In
In "Finders Keepers," the body of a diver is found in the ocean. The body is traced to a salvage barge that has a bloody handprint on it. After further investigation, it is discovered that the blood is not from the dead diver, but someone else murdered on the barge. In order to find the other vic...https://education.ti.com/en/activity/detail/numb3rs--season-3--finders-keepers--barging-in
NUMB3RS - Season 2 -"Hot Shot" - A Stab in the Dark
In "Hot Shot," two victims of a possible serial criminal are found. Charlie uses kernel density estimation as a method for predicting a change in behavior to indicate a connection between the victims and the criminal.https://education.ti.com/en/activity/detail/numb3rs--season-2-hot-shot--a-stab-in-the-dark
NUMB3RS - Season 2 - "Assassin" - Experimenting with Paper Airplanes
In the episode "Assassin," Charlie and Larry discuss a paper airplane contest and some factors that affect the flight of a paper airplane. Because it is much simpler, a paper airplane can be easily modified and then tested to see how those changes affect its flight.https://education.ti.com/en/activity/detail/numb3rs--season-2--assassin--experimenting-with-paper-airplanes
