Laplace Analysis: The s-domain
Demonstrates the utility of symbolic algebra by using the Laplace transform to solve a second-order circuit. The method requires that the circuit be converted from the time-domain to the s-domain and then solved for V(s). The voltage, v(t), of a sourceless, parallel, RLC circuit with initial co...https://education.ti.com/en/activity/detail/laplace-analysis--the-sdomain
How Salty Is It?
Students learn to solve a real-world problem involving salt water. Students will determine the amount of sea salt needed to turn an aquarium into a simulated salt-water environment.

Hat Trick
Students learn to solve a real-world problem in economics. Students get to understand how surveys often use a sample of people rather than all of the people involved. They also learn how to make decisions based on the results of a sample survey.https://education.ti.com/en/activity/detail/hat-trick
Graphs and Fractions
Have students draw squares on graph paper and half some of the squares on the outside. Number all the squares and continue numbering with the halfs. Students are then instructed to create their own ratios such as: 4 halves to eight wholes of odd numbers etc. Encourage student's to be creative by ...https://education.ti.com/en/activity/detail/graphs-and-fractions
Football Scores
Students will determine the possible combinations of scoring events in a football game to reach a specific end score.https://education.ti.com/en/activity/detail/football-scores
Probability as Relative Frequency
In this activity, students use simulation to justify the concept of the Law of Large Numbers. They understand that as the sample size increases, the relative frequency of which an event occurs approaches the probability of that event happening. Students investigate the binomial and geometric prob...https://education.ti.com/en/activity/detail/probability-as-relative-frequency
Comparing Distributions of Univariate Data
Students compare univariate data distributions using statistical concepts like boxplots, stemplots, and histograms.https://education.ti.com/en/activity/detail/comparing-distributions-of-univariate-data
Mean As a Fair Share
This lesson introduces students to mean as a way to describe the center of a set of data. Often called the average, the mean can also be visualized as “leveling out” the data in the sense of “fair share”.https://education.ti.com/en/activity/detail/mean-as-a-fair-share-bc
Mean As A Balance Point
In this lesson, students calculate deviations from the mean, how far each value is above or below the mean. Students also focus on the balance point of a distribution, where the sum of the absolute deviations below the mean is equal to the sum of the absolute deviations above the mean.https://education.ti.com/en/activity/detail/mean-as-a-balance-point-bc
Describing Categorical Data - Advanced Placement
Students categorize data using tables and bar charts. They also determine relative frequencies.https://education.ti.com/en/activity/detail/describing-categorical-data--advanced-placement
The Normal Distribution
Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.https://education.ti.com/en/activity/detail/the-normal-distribution_1
Exploring Bivariate Data
Students graph scatter plots and understand the concepts of correlation and least-squares regression. They also perform transformations to achieve linearity in the data plot.https://education.ti.com/en/activity/detail/exploring-bivariate-data
Is it Normal
In this activity, students will use the idea of a normal distribution to pull together multiple areas of probability and statistics.https://education.ti.com/en/activity/detail/is-it-normal
Graphical Displays of Univariate Data
Students will sort data and construct stemplots, dotplots, histrograms, and frequency plots.https://education.ti.com/en/activity/detail/graphical-displays-of-univariate-data
Box Plots
In this lesson, students plot the two extreme values (minimum and maximum), the lower quartile (LQ), upper quartile (UQ), and the median (a five-number summary) on a number line to create a graph called is a box plot.https://education.ti.com/en/activity/detail/box-plots-bc
Summarizing Distributions of Univariate Data
