Randomization Teacher Resources

Random sampling is as easy as choosing numbers. Teams use random numbers to create a sample of book lengths from a population of 150 books. The groups continue by developing a technique to create samples to compare from two populations...

Learning isn't a random process. A well-designed interactive lesson helps classes make key conclusions about stratified random sampling. They calculate group percentages and use those percentages to decide on sampling totals.

Teach the concept of simple random sampling through an interactive lesson. Learners explore the concept by considering the strength of sampling methods. Size of the samples varies also as individuals determine which methods lead to the...

Shuffle the resource into your activity repertoire. Scholars use randomly-generated iPod Shuffle playlists to develop ideas about randomness. They use a new set of playlists to confirm their ideas, and then decide whether the iPod...

It takes a lot of planning to achieve a random result! Learners compare results of random assignment, and conclude that random assignment allows results to be attributed to chance. They also realize the set of random means...

There's some serious science behind farming! A quick video lesson presents the process of collecting a random field soil sample for analysis. Instruction includes what a random sample looks like as well as how to prepare the sample for...

Variables can vary in meaning. A reference material for AP® Statistics explains the difference between random and algebraic variables. It provides a hypothetical situation involving dice—great for use in a classroom situation.

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

Sample pennies to gain an understanding of their ages. The 16th installment of a 25-part series requires groups to collect samples from a jar of pennies. Pupils compare the distribution of their samples with the distribution of the...

Learn how to analyze probability distributions. The sixth installment of a 21-part module teaches pupils to use probability distributions to determine the long-run behavior of a discrete random variable. They create graphs of probability...

It turns out that coin tosses might not be random after all. A math professor explains the results of his work in a video from the Numberphile Coins series. Flipping a coin results in the original state (heads or tails) 51 percent of the...

You'll probably end up thinking about randomness the next time you eat fries. The 17th video in the Crash Course Statistics series uses an analysis of McDonald's french fries to look at the mean and expected value of random...

You don't need to be discreet about using the resource on discrete variables. In the fifth installment of a 21-part module, scholars explore random variables and learn to distinguish between discrete and continuous random variables. They...

Seventh and eighth graders solve and complete 20 various types of short answer problems. First, they write a brief description of themselves including those as stated. Then, learners categorize the type of sampling used in various...

Take a walk down random lane. Scholars learn about random walks, where a random process like flipping a coin determines the next move of the walk. The video explains the difference between recurrent and transient walks based on whether a...

What defines a random sample? Scholars learn how to collect a random soil sample from a large field. The narrator explains the importance of ensuring the sample is random and shows how to create a random sample before sending it to the lab.

In this statistics and probability worksheet, young statisticians solve and complete 13 different problems related to probability, percentages, and normal distributions. They consider data models, assumptions about the models, and find...

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. 

Hopefully, there's nothing random about the decision to use the resource. Scholars view an informative video on random sampling. They watch as the narrator works through several examples on the topic.

Work it out — find the average time clients spend at a gym. Pupils use a table of random digits to collect a sample of times fitness buffs are working out. The scholars use their random sample to calculate an estimate of the mean of the...
