Students will develop an understanding of sampling distributions by exploring the methods used to estimate the number of German tanks in existence during WWIIhttps://education.ti.com/en/activity/detail/the-german-tank-problem
Slope - Confidence Interval and Hypothesis Test
This lesson involves investigating the confidence interval and hypothesis test for the slope of a regression line.https://education.ti.com/en/activity/detail/slope--confidence-interval-and-hypothesis-test
SD: Measure of Spread
This lesson is intended as an introductory activity to the concept of standard deviation.https://education.ti.com/en/activity/detail/sd--measure-of-spread
SD: How Far is Typical?
This lesson involves gaining a basic understanding of what standard deviation is measuring by examining the location of data around the mean.https://education.ti.com/en/activity/detail/sd--how-far-is-typical
Scatterplot Pulse Rates
This lesson involves creating a scatterplot and fitting a line to student pulse rates collected before and after exercise.https://education.ti.com/en/activity/detail/scatterplot-pulse-rates
Sampling
Students learn about each of the four types of random sampling methods and use the randInt command to find each kind of sample from a given population.https://education.ti.com/en/activity/detail/sampling_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
Stratified Sampling
This lesson involves determining which of three different sampling methods - a simple random selection design and two stratified selection designs - would be most beneficial in selecting a survey sample within a given context.https://education.ti.com/en/activity/detail/stratified-sampling
Inverse Variation
Students explore multiple representations of the inverse variation function, beginning with a geometric representation (a rectangle with fixed area), and progressing to a table of values, an algebraic expression, and finally a graph.https://education.ti.com/en/activity/detail/inverse-variation
Standard Error and Sampling Means
This lesson involves investigating the relationship between the standard deviation of a population, the area of a set of rectangles, and the standard deviation of the sampling distribution of sample mean areas of the rectangles.https://education.ti.com/en/activity/detail/standard-error-and-sampling-means
Square it Up!
Students investigate the method of least squares by adding the squares to a scatter plot and moving a line to find the minimum sum. Then they compare their line to the built-in linear regression model.https://education.ti.com/en/activity/detail/square-it-up
Finding Extraneous Solutions
Students will solve different types of equations step by step graphically. They will discover that some of the equations have an extraneous solution and they will investigate at which step in solving the equation that these "extra" solutions appear.https://education.ti.com/en/activity/detail/finding-extraneous-solutions
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
Exponent Rules
This activity allows students to work independently to discover rules for working with exponents, such as the Power of a Power rule. Students also investigate the value of a power whose exponent is zero or negative. As an optional extension, students investigate the value of a power whose exponen...https://education.ti.com/en/activity/detail/exponent-rules
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
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 and Spread
Students will recognize that the mean and standard deviation (SD) and the median and interquartile range (IQR) are two ways to measure center and spread.https://education.ti.com/en/activity/detail/center-and-spread
Mean Value Theorem
Calculate slopes of secant lines, create tangent lines with the same slope, and note observations about the functions and slopes.https://education.ti.com/en/activity/detail/mean-value-theorem_1
Candy Pieces
Students will be introduce to hypothesis testing. Students are given the number of pieces by color in a bag of candy.
