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...

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...

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...

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.

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...

Learners investigate why theoretical probability doesn't always match reality. The activity involves using Python 2.7 (or Sage) to set up a Bernoulli Trial. It also involves setting up a spreadsheet to simulate the Birthday Paradox....

Students collect and plot data on a graph. In this statistics lesson, students analyze the distribution of a sample and predict the outcome. They find the line of best fit and discuss what would make the sample larger.

Students calculate the normal distribution. In this statistics instructional activity, students use the normal distribution to estimate binomial distributions. They define when to use NP and n(1-p) to make approximations.

Fifth graders identify a set of data from a real world problem. In this statistics lesson, 5th graders identify the range, mode, median and mean using some manipulatives. They write words randomizing the letters.

An engaging game called, "Quarter, Nickel, and Dime" is presented in this math lesson. Players are given an envelope with slips of paper that represent the three coins. In pairs, they play the game 18 times, and the whole class charts...

Seventh graders explore random sampling by estimating the number of e's on the newspaper. They explain the possible error sources for this type of sampling, and compare the accuracy of sampling a small and large population. This is a...

What makes a good sample? Your classes collaborate to answer this question through a task involving areas of rectangles. Given a set of 100 rectangles, they sample a set of five rectangles to estimate the average area of the figures. The...

Young scholars construct data tables using the results of previous experiments. In this graphing lesson, students plot data and interpret the results. Young scholars discuss how they organized their data.

Students perform an experiment in which they will use a statistical method called `sampling' to count to a billion (and beyond). Students practice sampling by estimating the number of characters on a page from the classified section of a...

Young scholars use a book or magazine to research the use of letters. They complete a worksheet and compare their results.

Use the power of mathematics to find the number of red chips in a bag — it's a little like magic! The activity asks learners to collect data to determine the percentage of red chips in a bag. They calculate the margin of error and...

Students examine the concept of radioactive dating. In this radioactive dating instructional activity, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.
