Learning Goals

• I can describe patterns such as clustering, outliers, positive or negative association, linear association and nonlinear association.

• I can recognize if the data plotted on a scatter plot has a linear association.

• I can draw a straight line to approximate the linear relationship between the plotted points of two data sets.

• I can determine the equation of a trend line that approximates the linear relationships between the plotted points of two data sets.

• I can interpret the y-intercept and slope of an equation based on collected data.

• I can use the equation of a trend line to summarize the given data and make predictions about additional data points.
