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.
To calculate the value of the SDR in national currency (say, ABC), multiply the four exchange rates of the home country vis-a-Ã  vis the-basket currency (countries.i., E/ABC, USD/ABC, EUR/ABC, jpy AND/ABC) gbp with the basket values indicated in the above. tablehe exchange rates used by the IMF to calculate the official SDR are the noon rates in the London foreign exchange market. When the London market is closed, noon rates in the New York market are used, and Frankfurt fixing rates are employed when the New York market is also closed.
