You're Probably Right, It's Wrong - TI-83
In this activity, students perform a simulation to guess answers on a test and determine the experimental probability of passing the test. They then compare it with the theoretical probability.https://education.ti.com/en/activity/detail/youre-probably-right-its-wrong--ti83
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
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
Chi-Squared Tests
In this activity, students will look at a problem situation that involves categorical data and will determine which is the appropriate chi-square test to use: the chi-squared goodness of fit or the chi-squared two-way test.https://education.ti.com/en/activity/detail/chisquare-distributions
Describing Categorical Data
Students analyze the distribution of categorical data. They calculate percents and visually compare the data sets with a bar chart.https://education.ti.com/en/activity/detail/describing-categorical-data
Describing Bivariate Data (Two Quantitative Variables)
Students explore the relationship between two quantitative variables in bivariate data using various x-y plots. They compare the relationships for several categories on the same plot. Students calculate the correlation coefficient to measure the strength and direction of the linear relationship t...https://education.ti.com/en/activity/detail/describing-bivariate-data-two-quantitative-variables
Assessing Approximate Normality in AP Statistics
In this activity, students are sent 5 lists of data to study. The groups must use previously-discussed strategies for determining if each set could have reasonably come from a normal distribution.https://education.ti.com/en/activity/detail/assessing-approximate-normality-in-ap-statistics
A Move in the Right Direction
Students physically provide motion data that is collected by a CBL™ and then graph the data. They determine if they "moved in the right directions" by comparing their graph with those printed in the activity.https://education.ti.com/en/activity/detail/a-move-in-the-right-direction
Net Present Value and Internal Rate of Return
In this activity, students deal with cash flow and its present value, which is its worth in today's dollars. They will compare alternative investments by determining their Net Present Value and Internal Rate of Return. They will also determine, when called for, whether it is more profitable to le...https://education.ti.com/en/activity/detail/net-present-value-and-internal-rate-of-return
