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.
Format the numerical values. Select cells A2 through E8 and right-click on the selected cells. Select Format cells from the pull-down menu and click the Numbers tab. Select Time from the Category menu on the left of the dialogue box and select 1:30PM from the Type menu located to the right of the Category menu.Click OK.. Test the time sheet for accuracy. Type 8:00 in cell B2, 11:00 in cell C2 and 12:00 in cell D2. Select cells B2 through D2 and use the Fill Handle in cell D2 to drag the values down through to row 6. Use the Fill Handle in the lower right corner of Cell B2 to drag the formatting through to cell B8.
