Help your kids explore gender bias. Learners design and conduct a survey examining role responsibilities within families. They determine the percentage of responsibilities for males vs. females and graph the results. Then they analyze...

Young journalists learn how to identify bias in the news media.  First, they watch a video in which a Newseum expert identifies bias in a story about the 1919 Chicago race riots. They then use what they have learned to analyze a...

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...

Students explore statistics by conducting a scientific study. In this data analysis lesson, students conduct a class poll about popular foods of their classmates. Students complete a worksheet and discuss how bias opinions affect the...

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.

Students collect and sort rocks based on visible characteristics.  In this statistics instructional activity, students determine adequate sample size and categorize rocks based on characteristics.  The book Everybody Needs a...

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...

As part of a study of immigrant bias, high schoolers investigate the language used in blogs, readings, media reports, and current legislation whose language perpetuates xenophobia. They then consider ways they can get involved in...

Students demonstrate how the results of a poll or other scientific study can be biased by selecting special types of people to respond or by asking only certain questions.

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...

Students consider the advantages and disadvantages of various sampling techniques. They define a simple random sample and identify possible sources of bias in other types of samples. Answer Key included.

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...

Analyze characters and stories to identify stereotyping. Learners will examine the concept of character gender to evaluate bias in classroom story books. They are asked to read a story or play and change the gender of the character to...

Students take a sample of fish and try to determine how many fish are in the sea.  For this scientific sampling lesson, students explore the way scientists measure large areas of samples. Students record the distribution in a quadrant.

Students 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. Students...

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. 

Students practice formulating a hypothesis and designing an experiment to test the hypothesis. They identify several sampling techniques they can use to test their hypotheses.

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...

Show your classes how different means can represent the same data. Individuals collect household size data and calculate the mean. Pupils learn how handling of the data influences the value of the mean. 

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...

The difference between accuracy and precision is fundamental for high school science learners. Using test kits for nitrate concentration in water, they compare readings with each other. They consider the accuracy, precision, and bias of...

Learners engage in six activities to lead them through the process of conducting a thorough analysis of data. Pupils work with calculating standard deviations and z-scores, finding the area under a normal curve, and sampling...

Students explore how to select unbiased random samples as they choose report data to include on maps. They propose methods for choosing random numbers and discuss their advantages and disadvantages. They consider bias in science.
