Understanding energy usage requires knowing more than how much energy it takes to charge your cell phone. Scholars learn each text sent uses energy as does each video, game, and phone call. They observe the larger grid of data transfers...

One-hundred percent of those reading this sentence are human beings. Wait, what? With part eight in the Crash Course: Navigating Digital Information set, pupils learn how to think critically about statistics. Scholars discover how...

The teacher gives a very thorough explanation of numerical or quantitative data being anything where the answer to a question would be a number. Whereas any other answer might be considered categorical. She shows several different ways...

Introduce middle school scientists to scientific variables and the scientific method with a musical video. The song is a delightful parody of One Direction's "What Makes You Beautiful." It belts out the definitions of controlled,...

Sal trades his tablet for an Excel spreadsheet in this video, which covers fitting data to a line. Using a word problem about median income, he not only solves the problem but also demonstrates how to use scatter plots and Excel tools in...

No need to nap through the lesson. Given data on the number of naps two teachers take, learners calculate the mean, median, mode, and range, and then interpret their results in terms of the context. They then see how to determine the...

The teacher gives a very thorough explanation of numerical or quantitative data being anything where the answer to a question would be a number. Whereas any other answer might be considered categorical. She shows several different ways...

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,...

Sal helps with data organization in this video, which focuses on stem and leaf plots. Clarifying that "this is just one of many, many, many ways to visualize data that you will run into in your mathematical or statistical futures," he...

No one wants to be average, so mathematicians use the term mean instead of average. The video explains how to calculate the mean, how to calculate the percent error, and why this information is important. Finally, the video considers the...

A source that includes a graph may not always be the best reliable. A short resource highlights how graphs and charts can be misleading. Learners view actual graphs and note the way the graph is distorted to make a point. 

Starting with a set of values for the x and y variables, this video shows how to tell whether these points determine a linear or non-linear function. Sal first defines linear functions in terms of the change in y over the change in x,...

Mia teaches Sam how to create a bar graph, including forming a title, creating and labeling the axes, choosing a scale, and entering data. After viewing, data analysts can test themselves with seven follow-up questions and review...

Viewers will learn how to graph lines, such as y=2x+1. The instructor emphasizes the relationship between the x and y variables, creates an x/y table, and finally graphs the equation. A total of three examples are given in this video.

Here's a lesson sure to keep classes in line! A straight-to-the-point video explains the steps of creating a line graph from a table of data. Following the video, learners have plenty of opportunities to practice with the included...

Not just a bar graph—it's a double bar graph! Young scholars learn to read a double bar graph as they view the instructional video. The video highlights the individual data as well as shows a comparison between the two sets of data...

How can your class determine the relationship between experimental data? Learners discover how to express direct and inverse relationships through examples and sample problems in a video. The narrator takes data from tabular to graphical...

How do chemists use solubility data? Chemistry scholars learn the usefulness of solubility curves and how they are generated. The seventh part in a series of 14 discusses the solubility rules, plotting solubility data, and how pupils can...

Watch your pupils Excel at using spreadsheets to graph data by watching a video that covers how to graph data in a scatter plot using Microsoft Excel. The video also covers how to change titles, scales, and labels, as well as how to...

Elucidating the concept of box-and-whisker plots, Sal explains not only how to generate the diagram but also how to read one. He uses several examples to help young mathematicians become familiar with the format and explains its...

With so many types of graphs, don't let your learners get stuck figuring out which one to use. To track how Zoe spent her allowance, use this interactive lesson to review all the types of graphs and pick the best one to display the data....

Over a pizza dinner, RJ and Mia discuss how to use a circle or pie graph to represent data. After viewing, data analysts can use a Test Yourself feature to assess their own understanding. This is ideal for use in a flipped classroom lesson.

Another way to organize data beyond the stem and leaf plot - the histogram - is the focus of this lesson. Sal's objective is to introduce viewers to these methods of organization, making them familiar and straightforward, so students can...

The teacher illustrates two different exponential tables and explains what each one of them means. These are function tables, one demonstrates exponential growth and the other exponential decay. She clarifies how to analyze the...
