This tutorial takes you through the steps of creating a scatter plot, drawing a line-of-fit, and determining the correlation if any. [1:40]

A line-of-fit is a line that summarizes the trend in a set of data. In this tutorial, you'll see how to graph data on a coordinate plane and draw a line-of-fit for that data. [1:12]

This tutorial takes you through the steps of creating a scatter plot, drawing a line-of-fit, and determining if there is any correlation. [1:56]

This tutorial takes you through the steps of creating a scatter plot, drawing a line-of-fit, and determining the correlation if any. [1:53]

Simulators are a great way to model an experiment without actually performing the experiment in real life. This tutorial looks at using a simulator to figure out what might happen if you randomly guessed on a true/false quiz. [7:13]

Using a tree diagram is a helpful way to visualize all the possibilities from different options. Watch the step by step process of using a tree diagram. [6:16]

This lesson shows how to write the equation for a parabola when given three points. [9:22]

Trying to write an equation in point-slope form? Got a point on the line and the slope? Plug those values correctly into the point-slope form of a line and you'll have your answer. Watch this tutorial to see how it's done. [1:47]

Given a number line, how do you write the corresponding inequality? Watch this video for an explanation and example. [2:20]
