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...

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...

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...

To drill or not to drill? An informative unit has scholars first research the advantages and disadvantages of oil drilling in Alaska. They set up and conduct a sample survey to assess attitudes toward oil drilling in a specific...

Get to know the class much better. Scholars brainstorm a topic of interest and then design and conduct a class survey. Using the top responses, they create a game similar to Family Feud and take part in a class competition.

In this probability and statistics worksheet, students determine when a collected data or a graph of the data could be biased.  The one page worksheet contains four multiple choice questions.  Answers are included.   

Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

Students collect survey data on the prevalence of asthma in a community. They summarize and display the survey data in ways that show meaning.

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.

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. 

For this survey bias worksheet, students solve and complete 2 different types of problems regarding a survey. First, they identify various sources of bias. Then, students describe how to minimize bias in assessing statistical surveys.

In this categorizing data and bias worksheet, 9th graders solve 10 different problems that include various types of qualitative or quantitative data. First, they determine if the problem stated is univariate or bivariate data. Then,...

In this algebra worksheet, students identify bias as they analyze data. They solve word problems about sampling and surveys. There are 2 questions with an answer key.

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...

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...

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;...

A good understanding of local economics requires a lot of data. Scholars design and conduct an experimental survey to collect information about economic issues affecting their regions. They analyze their findings and prepare a...

Students work to develop surveys and collect data. They display the data using circle graphs, histograms, box and whisker plots, and scatter plots. Students use multimedia tools to develop a visual presentation to display their data.

Students develop and conduct a survey for their inventors unit. They create a five question survey and tally the survey results, and create a graph using Microsoft Word and Graph Club 2.0.

In this data handling worksheet, students determine biased and unbiased questions to surveys. They explore methods of data collection and design a data collection sheet. This two-page worksheet contains 3 multi-step problems.

For this probability and statistics worksheet, students determine when a survey or collected data could be biased.  The one page worksheet contains a combination of three multiple choice and free response questions.  Answers...

Analyze different types of graphs with learners. They conduct a survey and determine the mean, median and mode. They then identify different techniques for collecting data.

What better way to study survey design than to design your own survey! Bring a versatile data analysis project to your AP Statistics class, and encourage them to apply the practices from their instructions to a real-world survey...

Explore the power of mathematics through this two-week statistics unit. Pupils learn about several climate-related issues and complete surveys that communicate their perceptions. They graph both univariate and bivariate data and use...
