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.
As an example: if the initia â¦ l value is in cell A1 and the final value is in cell A2, the formula for percent change would be: =(A2-A1)/ABS(A1). You can EITHER multiply that value by 100 to get the percentage OR format the cell to display the number as a percentage.f you want to find the percentage of increase between A1 and A2, enter the original number in A1 and the larger number in A2. In cell A3, enter the formula =(A2-A1)/A1. This â¦ will give you a decimal, so if you want percent, you will need to multiply it by 100.
