Just how confident can we be with statistics calculated from a sample? Learners take this into account as they look at data from a sample of petroleum engineer salaries. They analyze the effect sample size has on a margin of error and...

Investigate the meaning of a sample proportion using this hands-on activity. Scholars collect data and realize that the larger the sample size the more closely the data resembles a normal distribution. They compare the sample proportion...

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

So what exactly is a random sample? The 15th part in a series of 25 introduces the class to the idea of selecting samples. The teacher leads a discussion about the idea of convenient samples and random samples. Pupils use a random...

Show learners how to use simulations and random sampling to reach conclusions with the last resource in a 25-part series. The assessment contains three scenarios, each with several parts, and covers comparing populations using...

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.

Do speed cameras help reduce accidents? Scholars investigate this question using a series of spreadsheet activities. Along the way, they learn about randomness, probability, and statistical analysis.

Manufacturers' claims may or may not be accurate, so proceed with caution. Here pupils use statistics to investigate the M&M's company's claim about the percentage of each color of candy in their packaging. Through the activity,...

One of the key questions in statistics is whether the results are good enough. Use an activity to help pupils understand the importance of sample size and the effect it has on variability. Groups collect their own sample data and compare...

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.

Don't leave learning to chance! Assess your class's understanding of random sampling and making inferences using questions from the experts at Smarter Balanced. As the seventh of nine parts in the Gr. 7 Claim 1 Item Slide Shows...

The 23rd segment in a series of 25 presents random samples from two populations to determine whether there is a difference. Groups determine whether they believe there is a difference between the two populations and later use an...

The penny arcade gets the statistics treatment in this fun probability investigation. A non-standard game of chance is described and then the class is set loose to find missing probabilities, determine common outcomes, and evaluate...

The validity of data depends on the strength of the sample. A collection of instruction and activities focuses on sampling distributions and the analysis of that data. Scholars learn about distribution tests such and Central Limit...

Students design models to simulate actual events using a random number generator on a calculator. They estimate the likelihood of a particular outcome using results of simulations. Answer Key included.

In this statistics worksheet, 11th graders complete word problems by analyzing data given to them. They answer the probability of an even occurring and reasons it should occur. There are 16 questions on this worksheet.

High schoolers 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. High...

Learners 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.

There are places in the US where a road cannot be found for miles! The lesson asks learners to use random longitude and latitude coordinates within the US to collect data. They then determine the sample proportion and confidence interval...

The way you use statistics can tell different stories about the same set of data. Here, learners use sets of data to determine which person sends the most text messages. They use random sampling to collect their data and calculate a...

Central to the idea of statistics is the central limit theorem. Scholars play an online Deadly Distribution game to discover the nature of statistics. Along the way, they learn about sample size, random sampling, distribution, and the...

Students explore the concept of fairness. In this fairness lesson, students play four probability games. Students determine who has the best chance of winning each of the four games. Students discuss which games gave an unfair advantage.

It's 268 words, but one only needs to consider 10 of them at a time. A data collection and analysis activity has learners investigate the lengths of words in the Gettysburg Address. They first self-select a sample of 10 words and...

In this chemistry worksheet, students focus upon the concepts of mean and standard deviation and how it is used in the laboratory to interpret data.
