Compare different random sampling types using an archaeological setting. Scholars collect data from an archaeological plot using simple random samples, stratified random samples, systematic random samples, and cluster random samples....

How random is random? Demonstrate the different random sampling methods using a hands-on activity. Pupils use various sampling techniques to choose a random sample of elements from the periodic table. They use the different samples to...

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.

Seventh grade statisticians randomly select five states and then determine the mean area. The class then works together to create a dot plot of their results. 

Students explore the concept of sampling techniques. For 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...

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

High schoolers investigate qualitative and quantitative data. In this statistics instructional activity, students gather data on heights and weights of people and graph the distribution. High schoolers discuss the differences between...

Young scholars work in groups with copies of the three photo images provided with the lesson. They make observations about mussels and clams. Students discuss reasons scientists use a representative sample of a population rather than the...

Third graders are introduced to statistical vocabulary. They complete an online activity that asks them to calculate the mean, median and mode for a set of data.

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

Students make origami frogs to race. After the race they measure the distance raced, collect the data, enter it into a chart. They then find the mean, median, and mode of the data. Next, students enter this data into Excel at which time...

Studnents examine the degree of biodiversity that exists in one's everyday environment, in order to develop an understanding of how scientists classify organisms and to explain why biodiversity is important for living things.

Students explore possible outcomes. In this math lesson, students list the possible pizza combinations they could offer on the menu of their new pizza shop. Students
