Believe it or not, sometimes statistics can be misleading. Introduce young statisticians to Simpson's paradox, where the same set of data can show opposite trends, depending on lurking variables.

This short but information-packed presentation begins with a thorough review of how to calculate mean, median, and mode of a given data set. What makes it a unique lesson is the follow-up example and presentation of how these measures of...

The finer points of telling the difference between cumulative and frequency histograms are laid out with clear examples for how to get from one to the other. From defining vocabulary through converting charted data to histogram form,...

Experimental design can be both incredibly intuitive and very high-concept when first introduced to learners. This video does a great job of discussing sampling methods and bias simply, without over-reducing...

Join Zoe as she calculates the average number of points RJ scored in his basketball games. This step-by-step presentation clearly models the procedure for finding the mean of a data set, including examples with both whole number and...

Zoe is curious how many goals her soccer team usually scores in a game. To answer the question, she walks through the process of finding the median of a data set in this step-by-step presentation. Examples are included that model how to...

Sam is running for class treasurer and Zoe wants to know if he won the election. Follow along as she counts up the votes and uses the mode to determine the winner. After viewing the presentation, work through the Try It! practice...

A straightforward math video provides an easy-to-understand explanation of probability. It is meant to be a first foray into the topic and would be useful in an elementary school classroom. The example given would be appropriate for use...

Transmit to your class what an unbiased sample is with this video. The video goes into detail about what an unbiased sample looks like, providing examples and listing several different types of random sampling. This could be used when...

With a well organized and clear explanation, this video will help students better understand independent and dependent events. Clear visual examples are provided and fully explaining.

Introduce your class to the value and practical applications of statistics. This is the first unit in a series completely focused on describing the three main activities involved with statistics. This video provides an overview of data...

Transmit to your class what an unbiased sample is with this video. The video goes into detail about what an unbiased sample looks like, providing examples and listing several different types of random sampling. This could be used when...

The data sample comes from the number of glasses of water consumed each day by 15 students. You are trying to find minimum, maximum, median, and quartile from this data set. Minimum is the smallest number that occurs, while maximum is...

So you have a data set and you want a visual diagram to help you analyze the data. Not sure how to draw it? The instructor illustrates four different ways to look at a frequency table: two tally tables, one line graph, and one bar graph....

It's all relatively simple. Young mathematicians learn about relative frequency by watching a short video. They see how to first determine relative frequencies, and then how to use these values to solve real-world problems.

Viewers must save the day for their favorite band by helping them find their instruments or the long-anticipated concert will be canceled. The show must go on, so get busy solving this riddle.

So you have a data set and you want a visual diagram to help you analyze the data. Not sure how to draw it? The instructor illustrates four different ways to look at a frequency table: two tally tables, one line graph, and one bar graph....

This lesson is an introduction to Multiple Regression Analysis or MRA, a statistical process used widely in many professions to estimate the relationship among variables. The aim of this video is to make it easier for students to...

In this video lesson students learn how to graph data on a coordinate plane and draw a line of fit for that data.

In this video lesson students look at a set of data, transfer the data into a two-way table and then use that table to make inferences about the data.

When you are trying to learn a particular characteristic of a large population, you need to be able to study an unbiased sample of that population to be able to draw accurate conclusions. Watch this video for an in-depth explanation. [5:04]

The main objective of this lesson is to motivate students' thoughts and get them excited about some probability concepts. The aim is to present probability theory in as simple a manner as possible. It is hoped that students will learn...

Watch and listen as the assistant general manager of a major league baseball team explains how he uses math in this video from KAET, Arizona PBS. A lesson plan and handouts are included. [7:43]
