Bellwork had students create a scatter plot from a table of data. They were to then draw a trendline and use this trendline to predict missing values then write an equation for the trendline.
The remainder of the period students learned about Linear Regression and Correlation Coefficient (Sec 2-4). Students were shown how to use technology (graphing calculator, spreadsheet software, and websites) to make a scatter plot, find the equation of the trendline, and to find the correlation coefficient.
