What's my line, anyway? A video covers the aspects of finding an equation of the best-fit line for a set of data. It works through plotting the points to drawing a line that appears to represent the data. The presenter suggests finding...

Organize your data on a graph. Use the data, pair them up as coordinate pairs, then graph them, resulting in a scatter plot. But how, you ask? Watch this tutorial to learn the step-by-step process needed to draw a scatter plot and...

You can use a scatter plot to determine if there is a positive, negative, or no correlation between the given data. After graphing data you need to find a line of fit, a line that best represents the data you've graphed. It will be the...

Scatter plots refer to a graph of given data. Scatter plots offer a way to look at information and allows the observer to analyze and interpret possible meanings and trends of the given data. Predictions can often be made based on the...

So you've got some x-values and some y-values and you want to make a scatter plot. First thing is to make a table for your x and y values. Then make ordered pairs and you can plot them.

Find a quick, concise explanation of how to solve systems of linear equations algebraically and graphically. Examples are given and clearly explained.

How do you determine the correlation in a set of data? Plot the data, find the line of fit, then use that line to determine if the correlation is positive, negative, or no correlation. This tutorial demonstrates that when a line of fit...

Twenty-eight problems present a variety of practice graphing ordered pairs. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View Solution" button to...

What is a line-of-fit? Given a data set, plot the ordered pairs on a graph. It looks like a scatter plot. Now estimate, and draw a line that best fits what the data represents. That is your line-of-fit.
