Candy Pieces
Students use a chi-square test for goodness-of-fit to determine if there is a significant difference between the proportions they find in the sample, and the proportions they would expect if the manufacturer produced equal proportions of each color.https://education.ti.com/en/activity/detail/candy-pieces
Interpreting Confidence Intervals
This activity is used in conjuntion with the famous M&M's experiment for introducing confidence intervals in AP Statistics. Navigator is used to allow each student to contribute the endpoints of a CI obtained from their own sample of M&M's. Quick polls are used to questions student confidence i...https://education.ti.com/en/activity/detail/interpreting-confidence-intervals
Difference Between Two Proportions
Students use confidence intervals to estimate the difference of two population proportions.https://education.ti.com/en/activity/detail/difference-between-two-proportions
Approximation of Pi Using Statistical Testing
Students will use a Monte Carlo method to collect data. This data, along with an area model of pi, will be used to approximate pi.https://education.ti.com/en/activity/detail/approximation-of-pi-using-statistical-testing
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
Analyzing Variance (ANOVA)
Students analyze variances of various data samples.https://education.ti.com/en/activity/detail/analyzing-variance-anova
A Simulation
In this activity, students use the CellSheet™ Application to simulate a probability event. This activity simulates an experiment performing a survey. Students can see that the results of a random survey can vary widely if a small sample size is used.https://education.ti.com/en/activity/detail/a-simulation
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.
