A transparent overlay for your scatter plot, including the line of best fit with two points on your line clearly labeled. Please indicate whether it is positive or negative correlation. You will then determine the equation of your line of best fit using the methods we used in class. All of the work should be shown on the poster.

If the fit is close there is a “strong” correlation and thus there would be more confidence using the line of best fit or equation to make predictions. A suggests strong correlation, B suggests weak correlation. If the slope of the line of best fit is positive (i.e. as one variable increases so does the other), there is …

A scatterplot with no correlation is one in which no consistent pattern exists to indicate a positive or negative correlation Line of best fit. A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.

Define the “line of best fit” as the model that best predicts of the outputs for given inputs. The line may contain some of the data points but it is not required to contain any of the points. With perfect correlation, the predicted output values are the same as the actual output values.
