Excel Lab 2: Regression and Goal Seek In this lab, you will use Excel to determine the equation of the model which best fits a set of ordered pairs obtained from data sets. You will enter data, graph the data, find the equation for the regression model, and then use that equation to make predictions for the dependent variable. You will use the goal seek to make predictions for the independent variable. Then you will consider how accurate your predictions...

Find some "real world" data. This data needs to have two sets of numbers that correspond to each other in an exponential pattern. Choose data with at least 10 pairs of data values. Caution: Do not select specific problems already in your text! Also, please be careful not to select exponential growth models that do not need data fitting such as doubling models. For example, if you already know a particular model grows by doubling each time period, then you...
