There is bias in many aspects of our lives, and math is no exception! Learners explore provided data to understand the meaning of biased and random samples. The resource includes various data sets from the same population, and...

Students collect and sort rocks based on visible characteristics.  For this statistics lesson, students determine adequate sample size and categorize rocks based on characteristics.  The book Everybody Needs a Rock is read to...

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...

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

Learners 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...

It's time to take a survey. After looking at an example of a survey on lunch preferences, groups design their own surveys. They consider the sample size and sampling technique, then conduct the surveys. As a final activity, they create...

Put your knowledge of sample surveys to good use. Pupils begin by conducting a survey of class members. They identify an appropriate topic and sampling technique; collect and organize their data; compute and analyze statistical measures;...

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.

Students analyze rocks. For this geology lesson, students collect rocks from the schoolyard and sort them according to various characteristics, such as color, size, and weight.

Students analyze rocks. In this rock classification lesson plan, students collect and analyze rocks that they find on the school premises. Students classify the rocks according to their physical characteristics in order to create a rock...

Students explore Earth science by identifying types of rocks in their schoolyard. In this geology lesson, students collect a group of rocks from their playground and categorize them based on color, shape and size. Students read the book...

Learners examine rocks. In this geology lesson, students collect rocks from the schoolyard and classify them by color, weight, and size. Learners use a rock guide to identify each of the rocks.

Students will collect and analyze a sample of rocks from the schoolyard. They will array the collected rocks by characteristics such as size, weight, and color, to see if any generalizations can be made about the types of rocks that can...

Your statisticians draw several samplings from the same data set, some randomized and some not, and consider the distribution of the sample means of the two different types of samplings. The exercise demonstrates that non-random samples...

Students analyze data they have collected themselves and by their classmates. In groups, they create data distributions to identify the highest, lowest and middle values. As a class, they discuss the concept of sample size and how it can...
