How confident are you? Explore the meaning of a confidence interval using class collected data. Learners analyze data and follow the steps to determine a 95 percent confidence interval. They then interpret the meaning of the confidence...

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

There are places in the US where a road cannot be found for miles! The lesson asks learners to use random longitude and latitude coordinates within the US to collect data. They then determine the sample proportion and confidence interval...

One of the key questions in statistics is whether the results are good enough. Use an activity to help pupils understand the importance of sample size and the effect it has on variability. Groups collect their own sample data and compare...

Conduct an experiment to determine the accuracy of pedometers versus pedometer apps. Class members collect data from each device, analyze the data using a hypothesis test, and determine if there is a significant difference...

Don't hit your head on the kitchen cabinet. Using previously collected female height data, scholars apply confidence intervals and tests of significance to perform a data analysis. They connect the data to the height of kitchen cabinets...

Pupils collect data and graph it. In this statistics instructional activity, students rate confidence levels by collecting data and analyzing it. They graph their findings on the Ti calculator.

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

Future statisticians and potential psychics first conduct an experiment to collect data on whether a person can tell if someone is staring at them. Statistical methods, such as hypothesis testing, chi-square tests, binomial tests, and...

Students observe diffusion of glucose through a cell membrane and research the function of chromium picolinate in glucose uptake into a cell. They conclude and understand the role of insulin and chromium picolinate in the uptake of...

Students use the net they make to dip macroinvertebrates at or below the surface. The flat side of the net allows pressure on the substrate so that organisms do not escape under the net. Two students hold onto the handles and submerge...
