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.
Based on http://www.gifted.uconn.edu/siegle/research/Normal/stdexcel.htm Calculating the Standard Deviation 1. Enter scores into a column in a spreadsheet. All scores must be entered, including any zeroes. A blank space will not be read as zero, but will instead be skipped over by Excel. Based on http://www.gifted.uconn.edu/siegle/research/Normal/stdexcel.htm 2. Once all of the scores have been entered, place the cursor in the cell where you would like the standard deviation to appear and click the mouse button. 3. Now look at the top of the Excel screen.
