In a scatter plot of weight versus height, what is typically observed?

• A trend where weight decreases with height

• No correlation at all

• A perfect straight line

What is a line of best fit?

• A line that connects all data points

• A line that represents the average trend in data

• A line that shows the maximum values

• A line that shows the minimum values

How does a curve of best fit differ from a line of best fit?

• It better represents data with a curved trend

• It represents a linear trend

• It shows no trend at all

• It connects all data points
