Baseball Relationships - Using Scatter Plots

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...

Bring the sun to your class! Young scholars analyze actual solar wind data in the second lesson of a five-part series. Their analysis includes speed, temperature, and density data.

Young statisticians use and interpret measures of center and spread such as mean, median, and mode as well as range. They use box plots to represent their data and answer questions regarding the correspondence between data sets and the...

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 demonstrates how to successfully use scatter plots and Excel...

Given a linear equation in standard form, find the x-intercept and y-intercept. In this video, Sal shows how one can set x = 0 and solve the y-intercept, and how you can set y = 0 and find the x-intercepts.

The instructor uses a computer graphing program to illustrate how a line changes slope by manipulating the slope values in the equation. He also manipulates the y-intercept value to see where the line crosses the y-axis.

After defining intercept, Sal solves a simple equation to identify each intercept and then plots the line on a graph. This video would quite nicely complement an introductory lesson on graphing.

What makes data big? The 38th installment in the series Crash Course Statistics provides a definition of big data and its origins. It shows various methods and resources on how to collect big data and how companies use big data for a...

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.

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...
