Estimating the Mean

Goal: The goal of this activity is for students to randomly draw words from an excerpt to estimate the mean length word count of the entire document. 

Inferences about two populations

Goal: The goal of this activity is for students to compare to samples from two different populations. They will make inferences based on what they find from their dot plot.

Outlier Activity

Goal: The goal of this activity is for students to interpret measures of central tendency when an outlier is present. They will also be able to identify which value is an outlier and create a boxplot as well.

Central Tendency and Measures of Dispersion

Goal: The goal of this activity is to allow students the ability to practice data collection and find measures of central tendency and dispersion. Wrap up questions will also allow for an insight into how each of these calculations are related to one another. Materials needed: 12 small bags of M & M’s (they can be the fun size or regular packs), calculator and the M & M worksheet and answer sheet.

California Adventures- Central Tendency and Variation

Earth Day Math

This powerpoint presentation for Earth Day Mathematics Lesson touches on many mathematical concepts such as volume, estimation, mean (average), measurement, and unit conversion. Students work in cooperative groups to find the approximate volume of rubber that a small business has 'rescued' from a local landfill. Alternate application ideas provided.

Average Athletics

One of the measures of central tendency is the mean/average. Many do not know much about the average other than it is calculated by "adding up all of the numbers and dividing by the number of numbers". This activity is designed to help students get a conceptual understanding of what an average is and not just how to calculate a numerical value.
