Scatter plots tell a story about the data — you just need to be able to read it! Building from the previous lesson in the series where learners created scatter plots, they now learn how to find associations in those scatter plots....

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...

Learners analyze multiple strategies of multiplication: clustering, area model, breaking apart/decomposing, etc. They create their own strategies to approaching multiplication problems and share them with their classmates. Discussion...

This worksheet has learners solve five problems in which groups of 10 pictured items are circled and the rest counted. Pupils write the number (under 20). What distinguishes this work from other counting worksheets is that the objects...

First graders practice rounding 4 digit numbers using place value concepts. In this estimating sums and differences lesson, 1st graders explore clustering, rounding, and front end estimation as methods for rounding decimals.

Investigate the relationship between height and arm span. Young statisticians measure the heights and arm spans of each class member and create a scatter plot using the data. They draw a line of best fit and use its slope to explain the...

Is there a relationship between height and the number of siblings? Classmates collect data on their heights and numbers of brothers and sisters. They apply statistical methods to determine if such a relationship exists.

How do doctors predict a child's future height? Scholars use one case study to determine the height of a child two years into the future. They graph the given data, determine the line of best fit, and use that to estimate the height in...

Pupils use the provided census data to guess the future height of a child. They organize and plot the data, solve for the line of best fit, and determine the likely height and range for a specific age. 

Mortgages, payments, and wages correlate with each other. The short assessment presents scatter plots for young mathematicians to interpret. Class members interpret the scatter plots of price versus payment and wage versus payment for...

It is positive that how one performs on the first test relates to their performance on the second test. The three-question assessment has class members read and analyze a scatter plot of test scores. They must determine whether...

The bounce of a golf ball changes the result in golf, mini golf—and a great math activity. Scholars graph the height of golf ball bounces before finding a line of best fit. They analyze their own data and the results of others to better...

Pupils explore the concept of interpreting data. In this interpreting data lesson, students make a line plot of themselves according to the number of cubes they can hold in their hand. Pupils create their own data to graph and interpret....

Eighth graders discuss how data is collected and participate in data collection through a survey. They complete a scavenger hunt on the Internet to gain understanding of the data measures mean, median, mode, and range.

In this lunar meteorite impact worksheet, students read about the dangers of meteorite impacts while exploring the moon. Students solve 7 problems including finding the area of the side of the moon that faces the Earth, calculating the...

Learners use several examples to create a method for adding and subtracting fractions with unlike denominators. They present these methods to the class and then practice applying methods to sample problems.

Students develop strategies to organize data while following teacher demonstration. They calculate the mean, median and mode of a data set while determining the relationships between the numbers. They analyze data from tables and double...

Learners explore the concept of statistical data. In this statistical data lesson, students read an article about the dangers of peanut butter to those who are allergic. Learners perform a taste test of two different brands of peanut...

Students explore the concept of stem and leaf plots.  In this stem and leaf plots lesson, students plot the 50 US states' capitals on a stem and leaf plot according to the first letter of each state.  Students compare...

Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.

This page is a math home page that includes information on all topics of probability and statistics.

[Free Registration/Login Required] This lesson uses clustering to explore the concept of mean, median, and mode of a set of data and calculates the arithmetic mean.

Contains a definition for what cluster sampling is, when it is used, and also provides an example situation for when it would be used.

An encyclopedia entry on cluster sampling details what it is, how it is different from stratified sampling, and provides a discussion on geographical cluster sampling.
