Coke vs. Pepsi Taste Test: Experiments and Inference about Cause part of Teaching Methods:Teaching with Data Simulations:Examples
The Coke vs. Pepsi Taste Test Challenge has students design and carry out an experiment to determine whether or not students are able to correctly identify two brands of cola in a blind taste test. In the first ...

Reese's Pieces Activity: Sampling from a Population part of Teaching Methods:Teaching with Data Simulations:Examples
This activity uses simulation to help students understand sampling variability and reason about whether a particular samples result is unusual, given a particular hypothesis. By using first candies, then a web applet, and varying sample size, students learn that larger samples give more stable and better estimates of a population parameter and develop an appreciation for factors affecting sampling variability.

How Big is a Trillion? part of Teaching Methods:Teaching Quantitative Reasoning with the News:Examples
Perhaps the first skill needed for successful quantitative reasoning is the ability to understand a single number. Newspaper headlines over the last year have used some amazingly large figures when discussing the ...

Calculating and Comparing Tax Rates part of Teaching Methods:Teaching Quantitative Reasoning with the News:Examples
This example focuses on six letters to the editor. All six letters attempt to describe and compare the amount of taxes paid on two different incomes: ,000 and 0,000. Tax rates are expressed in absolute ...

Cost Effectiveness of Increased Fuel Efficiency part of Teaching Methods:Teaching Quantitative Reasoning with the News:Examples
In this example students examine and critique an argument which implies that it is not cost effective to pay for an automobile with increased fuel efficiency. Using a few reasonable assumptions shows that some of ...

World Population Activity I: Excel part of Teaching Methods:Mathematical and Statistical Models:Examples
(Activity 1 of 2) This activity is primarily intended as an introductory tutorial on using Excel. Students use Excel to explore population dynamics using the Logistic equation for (S-shaped) population growth.

Something is Askew at Mammoth Cave National Park part of Teaching Methods:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum/Geology of National Parks module. Students use the geometric mean and multiplicative standard deviation to examine the right-skewed distribution of nutrient concentrations in water-quality data at Mammoth Cave National Park.

What are the Winds Blowing into Mammoth Cave? part of Teaching Methods:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum/Geology of National Parks module. Students estimate the net volume of pollutants flowing into the Houchin's Narrows entrance of Mammoth Cave using actual air-flow and air-quality data from the park.

Using an Applet to Demonstrate Confidence Intervals part of Teaching Methods:Teaching with Data Simulations:Examples
Students will utilize an applet to further expand their knowledge of confidence intervals.

Simulating Size and Power Using a 10-Sided Die part of Teaching Methods:Teaching with Data Simulations:Examples
This group activity illustrates the concepts of size and power of a test through simulation. Students simulate binomial data by repeatedly rolling a ten-sided die, and they use their simulated data to estimate the size of a binomial test.
