Meaning of Power
In this lesson, samples are generated from a population for a particular hypothesis test, leading to the conjecture that the null hypothesis is actually false.https://education.ti.com/en/activity/detail/meaning-of-power
Chi-Square 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.https://education.ti.com/en/activity/detail/chisquare-tests
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

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
Chi-Square Distributions
Students compare the Chi-Square distribution to the standard normal distribution and determine how the Chi-Square distribution changes as they increase the degrees of freedom.https://education.ti.com/en/activity/detail/chisquare-distributions_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
Local Linearity
Visualize the idea of derivative as local slope.https://education.ti.com/en/activity/detail/local-linearity
Properties of Logarithms
Logarithms are just another way of writing exponents. Just like exponents, logarithms have properties that allow you to simplify expressions and solve equations. In this activity, students Will discover some of these properties by graphing and confirm them with algebra.https://education.ti.com/en/activity/detail/properties-of-logarithms
Solving Systems of Linear Equations with Row Reductions to Echelon Form on Augmented Matrices
This activity shows the user how to interpret a system of linear equations as an augmented matrix, row reduce the matrix to echelon form, and interpret the output to give a unique solution, generate infinite solutions, or conclude no solutions exist. The activity also shows how to check unique so...https://education.ti.com/en/activity/detail/solving-systems-of-linear-equations-with-row-reductions-to-echelon-form-on-augmented-matrices
Cancer Clusters
Students will investigate cancer incidence rates in a number of states. Hypothesis testing is introduced and used along with a two-proportion z-test to compare cancer rates.
