Emerging statisticians develop the ability to make inferences from sample data while also working on proportional relationships in general. Here, young learners examine samples for bias, and then use random samples to make...

Using a 2002 California Gray David recall vote as an example, young statisticians  identify sources of bias in samples and find ways of reducing and eliminating sampling bias. They consider ways to select random samples from a...

Some say that you can make statistics say whatever you want. It is important for learners to recognize these biases. Pupils learn about sample bias and the different types of samples.

Statistics can be manipulated to say what you want them to say. Teach your classes to be wise consumers and sort through the bias in those reports. Young statisticians study different statistical reports and analyze them for...

Space science stars journey through our night sky and take virtual photos of galaxies to investigate simple random samples. Higher math is used to analyze the data collected. Copy the evaluation/assessment questions onto a handout...

Learners explore the concept of sampling techniques. In this sampling techniques lesson, students identify possible sources of bias in situations such as phone polls, supermarket surveys, and drawing names from a phone book. Learners...

Students explore different methods of taking surveys and conducting polls and examine these methods for bias. They design and administer a sample survey, analyze the data and present their findings to the class.

To understand how biased data is misleading, learners analyze survey data and graphical representations. They use that information to design their own plans to collect information on consumer thoughts about Chocolicious cereal. 

It's 268 words, but one only needs to consider 10 of them at a time. A data collection and analysis activity has learners investigate the lengths of words in the Gettysburg Address. They first self-select a sample of 10 words and...

Sixth graders examine how to select samples and apply them to an experiment. In this sampling lesson, 6th graders use a bag of yellow and blue cubes to take a sample. They predict how many of each color there are the bag. They set up and...

Students define random sample and complete surveys. In this algebra instructional activity, students create surveys and define the way people analyze these results. They discuss random sample as it relates to the Great Depression and...

Students identify a question to generate appropriate data and predict results. They distinguish between a total population and a sample and use a variety of methods to collect and record data. Students create classifications and ranges...

Students interpolate, extrapolate, and make predictions from given information. They present results and conclusions from given data using basic statistics. Pupils create a survey from a critical question and decide which sampling...

Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

Take your enthusiastic ecologists outdoors to explore the biodiversity right in their own schoolyard! In preparing for this activity, it may be worthwhile to research websites with local flora to help in the plant identification...

Young scholars investigate threee types of maps. In this algebra lesson, students idenitfy different maps and explore how they relate to the area keeping cllimate and topography in mind. They discuss maps used to navigate land. air...

Ninth graders assess the accuracy and reliability of current survey data and how it is represented. They design a survey, collect data, and use technology to analyze the data and present the results. Students examine scatter plots and...

Students design a survey of the public as to what type of food should be served in restaurant that they are "planning" to open.

Students compare different aspects of investing money from traditional savings accounts to money market accounts. They research investment accounts at local banks and compare them.

Twelfth graders test their knowledge of Algebra II and Trigonometry.  For this Algebra II/Trigonometry lesson, 12th graders are provided with a copy of an Algebra II/Trigonometry Regent Exam from the fall of 2009.  The exam has...

The exercise demonstrates that judgment (non-random) samples tend to be biased in the sense that they produce samples that are not balanced with respect to the population characteristics of interest. Students will estimate the mean...
