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
Using the TI-83/84 to Explore the Binomial Theorem
This lesson will introduce students to the binomial theorem through a variety of activities. Pascal's triangle and probabilities will be explored through problem solving. The binomial theorem, combinations formula, and the binomial probability function will also be explored. Students will dis...https://education.ti.com/en/activity/detail/using-the-ti8384-to-explore-the-binomial-theorem
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
The Graphing Calculator Connection: Problem Solving and Investigations
Over 30 reproducible, motivating investigations designed especially for middle school students to use with any TI Graphing Calculator model.https://education.ti.com/en/activity/detail/the-graphing-calculator-connection-problem-solving-and-investigations
t Distributions
Students compare the t distribution to the standard normal distribution and use the invT command to find critical values for a t distribution.https://education.ti.com/en/activity/detail/t-distributions
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
