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.
We must find a way of telling Excel to use call B10 to divide by for each of the other 8 equations. Step 5. Absolute Cell Reference-You tell Excel to use one specific cell, and never move to another relative location in the calculations by using absolute cell reference..To specify the cell, place a dollar sign before the column letter and before the row number. Thus, $B$10 says always use cell B10.e must find a way of telling Excel to use call B10 to divide by for each of the other 8 equations. Step 5. Absolute Cell Reference-You tell Excel to use one specific cell, and never move to another relative location in the calculations by using absolute cell reference..
