Sampling Bias And the California Recall
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...

Using Random Sampling to Draw Inferences
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 inferences...
Curated OER
Designing Samples/Simple Random Samples
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.

Graphing Data
Seventh graders solve and graph 10 different problems that include various questions related to data on a graph. First, they create bar graphs to display the data given. Then, pupils determine the random sample of a population listing...
Flipped Math
Sampling Methods
Pupils watch a video to learn about different types of sample design and how to use technology to create a random sample. They discover different types of bias that may happen due to the sampling design or the questions. Learners use...

Galaxy Hunter - A Cosmic Photo Safari
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 for...
Curated OER
Designing Samples/Simple Random Samples
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...

Evaluating Reports Based on Data from a Sample
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 misleading...

Why Randomize?
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...

Chocolicious
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.

Mapping Data Made Manageable
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.
Curated OER
Sampling Snoops
Pupils practice formulating a hypothesis and designing an experiment to test the hypothesis. They identify several sampling techniques they can use to test their hypotheses.
