Scatter Graphs
Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

How Do You Make a Scatter Plot?
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.

What's a Scatter Plot?
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...

What Does it Mean To Have No Correlation?
What does it mean when a scatter plot graph shows that there is no correlation? Does it have something to do with the slope of the line of fit? Yes, it certainly does have to do with the line of fit. If the slope of the line is zero,...

How Do You Use a Scatter Plot to Find a Positive Correlation?
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...

What's Negative Correlation?
If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

How Do You Use a Scatter Plot to Find a Line of Fit?
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.
