Using Intercepts to Interpret Data

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

Analyze data using technology. Middle schoolers design data investigations, describe data, and draw their own conclusions. Then they select the best type of graph, graph and interpret the data, and look for patterns in trends. They also...

Students investigate poverty using graphs. In this algebra lesson, students collect data on the effects of poverty and use different rules to analyze the data. They graph and use the trapezoid rule to interpret the data.

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,...

Kick off the school year with some math fun! New classmates share information about themselves by using graphs and interpreting data. The goal is to use a general graph shape, such as linear or exponential, and create labels for the axes...

Learn about life in the Arctic while practicing how to graph and interpret data with this interdisciplinary instructional activity. Starting with a whole group data-gathering exercise, students are then given a worksheet on which they...

We have calculators, so why do we have to do this by hand? The video takes viewers through graphing scientific data by hand to create a scatter plot. The process includes labeling axes, writing an appropriate title, determining a scale,...

Represent data graphically. Allow your class to explore different methods of representing data. They create foldables, sing songs, and play a dice game to reinforce the measures of central tendency.

Not all data is the same. Using the interactive, pupils compare data represented in two different ways. The learners develop an understanding of the difference between discrete and continuous data and the different ways to represent each...

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.
