How Do You Use a Scatter Plot to Find No Correlation?

Correlation tells you how data points are related to each other
To make a scatter plot, graph each data point as an ordered pair
A line of fit is a line you can draw that best represents the data on a scatter plot
The slope of the line of fit tells you what the correlation will be
Since our line of fit is a horizontal line, it has a slope of 0
That means our data have no correlation

1. The value for x becomes the x-coordinate and the value for y becomes the y-coordinate
2. So for instance, the first point would become the ordered pair (1,10)
1. A scatter plot will give you a visual representation of the data
2. Then it will be easy to see the relationship between the data points
1. A line of fit is a line you can draw that best represents the data on a scatter plot
1. You want it to go through the middle of the data as much as possible
2. That way it will best represent as many of the points as possible
1. The correlation tells us how the data points are related to each other
2. Correlation can be positive, negative, or 0
1. If the slope of the line of fit is positive, we have a positive correlation
2. If the slope of the line of fit is negative, we have a negative correlation
3. If the slope of the line of fit is 0, we will have a horizontal line which means we have no correlation
1. The slope of a horizontal line is always 0
1. This means that there is no relationship between the data points that we can tell from this graph

Draw a scatter plot from the following data. Then determine if there is a positive, negative, or no correlation.
