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...

Using your completed table, you can calculate the Spearman correlation in two different ways. One way is to use the Pearson correlation formula on the ranks of the data. When you do this, you get rs - -0.62. The second way to calculate the Spearman correlation is to use the following formula: Is = 1 - 62D2 n(n2 - 1) In this formula, D represents the difference between ranks for each individual. Using this formula, you get rs - -0.51....
