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...

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...

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...

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...

Students define random sample and complete surveys. For this algebra lesson, students create surveys and define the way people analyze these results. They discuss random sample as it relates to the Great Depression and come up with their...

Learners 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.

In this probability and statistics worksheet, students solve independent and dependent probability problems. They identify the mean, mode and range of a set of numbers. This two-page worksheet contains five probability problems.

Learners define sample, describe a random sample, and discuss what compromises a sample. They determine a sample size to estimate a population characteristic with confidence.

High schoolers investigate the greenhouse effect and examine the potential effects of climate change in the Arctic. They construct a mini-greenhouse and test its effect on temperature, analyze historical climate statistics, and conduct...

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

In this probability instructional activity, learners solve and complete 16 various types of problems related to statistics. First, they determine the probability of the statistics that are true as shown. Then, students find the...

In this statistics learning exercise, students solve and complete 10 different types of problems. First, they determine the probability of various actions described. Then, students describe an appropriate model for the number described...

In this probability and statistics worksheet, students find compound dependent and independent probability of given situations. They identify the mean, mode, range and median of sets. This two-page worksheet contains explanations,...

In this business and statistics worksheet, students read real-life business problems, arrange data, and identify the probability method best used to determine the answer. They identify the type of random sample, draw stem-and-leaf plots,...

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...

Young scholars gather appropriate information for simple statistical analysis. Then they will calculate probability working with a piece of literature that makes this lesson ideal for teaching across the whole curriculum.

Middle schoolers explore and design ways to collect data through simulations and random samples. They perform two experiments to determine the answers to various probability problems, and present the data/graphs in the form of a...

In this 4th grade statistics worksheet, students complete a total of 7 problems. An answer key is provided; problems are related to statistics.

In this probability worksheet, 11th graders solve problems using simple random sample, cluster sample, bias, population and systematic sample. They match the questions to its definition.

In this statistics worksheet, students examine different events after translating the word problems into equations and choose which event is most likely to occur. There are 14 questions with an answer key.

In this using probability to solve word problems worksheet, students use statistics, averages, and even numbers, to problem solve. Students solve six problems.

In this math for fourth grade statistical charts worksheet, 4th graders answer 7 multiple choice questions in standardized test format about data, charts and graphs.

Students see that there are mathematical rules that can affect our use of the English language. Calculate the probability of picking any letter at random from a piece of English literature.

How accurate is data collected from a sample? Learners answer this question using a simulation to model data collected from a sample population. They analyze the data to understand the variability in the results.
