Comparing Double Line Graphs and Box Plots
Students are given a data table and are asked to look at the double-line graph to understand the trends that they observe in regards to indoor and drive-in movie theaters. They are then asked to investigate the trends that are presented to them when a box plot is created with the same data. Stud...https://education.ti.com/en/activity/detail/comparing-double-line-graphs-and-box-plots
F Distribution
Students study the characteristics of the F distribution and discuss why the distribution is not symmetric (skewed right) and only has positive values. Students then use the Fcdf command to find probabilities and to confirm percentiles. They move on to find critical values and then compute a conf...https://education.ti.com/en/activity/detail/f-distribution_1
Exploring the Normal Curve Family
Students will investigate the relationship of the equation of a normal curve to its graph. They will use a slider to change the values of two parameters, m and s, to investigate their effects on the normal curve, noting in particular that m represents the location of the mean and that s represent...https://education.ti.com/en/activity/detail/exploring-the-normal-curve-family_1

What! A Mistake!
Students learn about Type I and Type II errors. Then, for a given scenario, students will calculate the probabilities of errors and the power of the test.https://education.ti.com/en/activity/detail/what-a-mistake_1
Effective Blocking
This lesson involves investigating the effectiveness of two mosquito sprays in a large tract of land by using three different experimental designs - one randomized design and two randomized block designs.https://education.ti.com/en/activity/detail/effective-blocking
Solve Me - One and Two-Step Inequalities
Students will use the TI-Nspire CAS to check their steps used to solve one and two-step inequalities. They will also use the solve feature to verify that they have the correct solution at the end of each problem. While solving inequalities, many students make careless mistakes with simplifying...https://education.ti.com/en/activity/detail/solve-me--one-and-twostep-inequalities
Solve Me - Multi-Step Equations
Students will use the TI-Nspire CAS to check the steps they used to solve multi-step equations and equations with variables on both sides. They will also use the solve feature to verify that they have the correct solution at the end of each problem. While solving equations, many students make ...https://education.ti.com/en/activity/detail/solve-me--multistep-equations
Goodness-Of-Fit
Students test claims of whether given distributions "fit" theoretical distributions. Students will work through two problems, one in which the theoretical proportions of each category are the same and one in which they are not. Students will use spreadsheets to calculate test statistics and the I...https://education.ti.com/en/activity/detail/goodnessoffit_1
Testing Claims About Proportions
Students find z-scores and critical values to test claims about proportions. To verify the results, they find P-values by either finding the area under the curve with the Integral tool, or by using the 1-Prop z Test command.https://education.ti.com/en/activity/detail/testing-claims-about-proportions_1
Claims About Two Proportions
Students test claims about two proportions by calculating test statistics, critical values, and P-values, for both one- and two-tailed tests.https://education.ti.com/en/activity/detail/claims-about-two-proportions
Linear Inequalities
Students first look at tables of values to see that inequalities are true for some values of the variable and not for others. They then graph simple inequalities, comparing the handheld output with graphs they create on paper. The last two problems have students solve one-step linear inequalities...https://education.ti.com/en/activity/detail/linear-inequalities
Relating Rates - IB
Students are given a situation of water draining out of a cylindrical tank in order to explain the process of solving related rates questions.https://education.ti.com/en/activity/detail/relating-rates_1
Center of Mass
Students will identify and interpret the mean geometrically as the location of the coins on the ruler such that the sum of the distances on either side of the mean is the same.https://education.ti.com/en/activity/detail/center-of-mass
Candy Pieces
Students will be introduce to hypothesis testing. Students are given the number of pieces by color in a bag of candy. They are asked if they think the bag could have come from a manufacturing process designed to produce equal proportions of each color. They will then use a chi-square test for goo...https://education.ti.com/en/activity/detail/candy-pieces_1
Comparing Prices
Students will compare average U.S. gasoline prices per gallon for two years. Then they will use the mean and standard deviation (SD) and the median and interquartile range (IQR) to measure the center and spread of price data.https://education.ti.com/en/activity/detail/comparing-prices
Confidence Levels for Proportions
This activity involves generating a confidence interval for a population proportion from a random sample of size 100 and considering how certain one can be that this interval contains the actual population proportion.https://education.ti.com/en/activity/detail/confidence-levels-for-proportions
Confidence Levels for Means
Students will interpret a confidence level as the average success rate of the process used to produce an interval intended to contain the true mean of the population. Students will recognize that as the confidence level increases, on average, the confidence interval increases in width.https://education.ti.com/en/activity/detail/confidence-levels-for-means
