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.
SUMMARY. In Microsoft Excel, there is no built-in function to calculate the percentage of change from one value to another. However, you can use the following formula to calculate the percentage change. where. represents the value that the percentage of change is based on, and. represents the value that has changed.You may also use the following alternate formula: To display the resulting value as a percentage value, format the cell containing the formula with a percentage format.n Microsoft Excel, there is no built-in function to calculate the percentage of change from one value to another.
