Data Sampling
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.

Leveled Problem Solving Sampling Methods
In this sampling methods worksheet, students solve the six problems using sampling methods and determining if the results are biased or unbiased.
Curated OER
Surveys and Samples
For this surveys and samples worksheet, students discover data collection techniques and write their own survey questions. Students use random sampling, convenience sampling, and systemic sampling and analyze their results.

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...

Strict Parents
Are your parents or guardians strict? That's an interesting question many of your pupils are probably interested in discussing. How do you design a study directed at your high schooler to gain insight into that question? How do you...

The Science of Surveys
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...
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.

Surveys and Estimating Large Quantities
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...
Curated OER
Samples and Stats
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.
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...

Sampling for a Rock Concert
Over the course of three class periods, middle schoolers design an experiment to provide learner input to administration about which rock band to invite to play at school. They practice several random sampling exercises, all well...
Curated OER
Recycling Survey
How many people really recycle recyclables and how do they feel about it? High schoolers create a survey to find out. Once they agree on what questions to include, they each interview four people outside of the classroom. They combine...

Annual Wetland Plant Diversity Survey
High schoolers locate an area of marsh and, by measuring the total number of individual plants in a sample area, determine whether purple loosestrife population density is correlated to the total plant diversity of the community. They...
Curated OER
Fisheries Research Methods
Students explore how scientists keep track of fish populations and why it is important to do so. They describe three methods currently used to sample fish populations. They participate in activities to simulate several of the sampling...

Data Handling
In this data handling learning exercise, students determine biased and unbiased questions to surveys. They explore methods of data collection and design a data collection sheet. This two-page learning exercise contains 3 multi-step...
Curated OER
Opinion Surveys
Students examine the factors that affect the accuracy of opinion surveys. They calculate probability and chance using data they have collected. They practice reading tables and graphs as well.
