Statistical Analysis (Excel)1. Register and Normalize your data.2. Put the pixel values (the same pixel) in Excel.3. “Sort” values in ascending order (easier to read).4. Below the list create a cell that calculates the mean.(=sum(begin:end)/count(begin:end)• Make a cell to hold N, the total number of values(count(begin:end). You will need this later.5. In the column next to the values create a new columnfor the residuals. (value-mean)6. Now calculate the residuals squared in the thirdcolumn.• Below the cell that holds the mean value, you can createanother cell that is the sum of the residuals squared column.Call it SumResSqrd.7. Finally create a cell that has the formula to calculateone standard deviation of your set of values.• =sqrt((N-1)*SumResSqrd)
Statistical Analysis (Excel)<strong>Making</strong> a Histogram1. From your ordered (ascending) set of values,create another column of bin values that gofrom just a little less than the smallest value ofyour data to just a few bins more than yourlargest value.2. Under “Tools” in Excel there is “Data Analysis”3. Find the “Histogram” option.4. Highlight and define the column for the valuesand then the column for the bins.5. Excel will do everything else to calculate thefrequency of values and create the graph.
