Students learn about push-pull factors and corresponding population mobility patterns. This lesson plan was given the 2006 Geography Excellence in Media (GEM) Award by the National Council for Geographic Education (NCGE).
ED50V10 (Readme) is an Excel add-in for calculating IC50/EC50 values. Input your data in the left columns, and your results will be shown in the right half of the Excel table. To calculate IC50, input 50 in the INTERPOLATE... table (highlighted in blue), the result will be shown on the right (highlighted in green).inear Regression. The simplest estimate of IC50 is to plot x-y and fit the data with a straight line (linear regression). IC50 value is then estimated using the fitted line, i.e., Y = a * X + b, IC50 = (0.5 - b)/a. Log transformation. Frequently, linear regression is not a good fit to dose-response data.
= npv (our discount rate /12 as the rate is compounded monthly, the range of values you want to be considered)+the initial investment, in our case the starting 100,000$. Step 3. Excel will calculate for you the Net Present Value of this investment.Step 4. Go to the cell that you want to hold the NPV result for comparison, and type: =npv(the same discount rate/12,the range of values)+the initial investment. Hit Enter.Step 5. Excel will calculate for you the Net Present Value of this investment.tep 3. Excel will calculate for you the Net Present Value of this investment. Step 4.
