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...

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...

In this statistics and probability activity, 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...

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...

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...

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...

In this probability and statistics worksheet, pupils 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.

Seventh and eighth graders solve and complete three various types of problems. First, they find the median rate using the box-and-whisker plot shown. Then, learners describe the inter-quartile range. In addition, they determine whether...

Quickly assess basic understandings of statistics and probability. The resource contains five quick tasks from the probability and statistics domain. The questions range from finding simple conditional probabilities to measures of...

Candy is always a good motivator! Use this collection of M&M's® experiments to introduce statistics topics, including mean, standard deviation, nonlinear transformation, and many more. The use of a hands-on model with...

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

Find the percent of middle schoolers who want the ability to freeze time. The 21st installment in a series of 25 has groups collect a random sample of respondents who answer a question about superpowers. Using sample statistics,...

The test may say you have cancer, but sometimes the test is wrong. The provided task asks learners to analyze cancer statistics for a fictitious town. Given the rate of false positives, they interpret the meaning of this value in the...

"Statistics are no substitute for judgment" - Henry Clay. Young mathematicians use provided statistics from a soda taste test to explain why conclusions are faulty. They devise a new test that would be more appropriate than the one given.

Determine whether there is a difference between two grades. Teams generate random samples of two grade levels of individuals. Groups use the mean absolute deviation to determine whether there is a meaningful difference between the...

For 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,...

Young analysts use real (provided) data from a class's test scores to practice using statistical tools. Not only do learners calculate measures of center and spread (including mean, median, deviation, and IQ range), but...

In this business and statistics worksheet, learners 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...

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

For 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 probability learning exercise, students 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 conditional...

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 statistics worksheet, 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 and...
