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...

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 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.
