B. Calculate the uncertainty in each ratio. C. Calculate the weighted average (and its associated uncertainty) of your ratios determined in the data table. where w, ,and AX (AX) D. Use Excel to determine the variability of your data set (standard deviation) and uncertainty of the mean. E. Compare the uncertainty in the mean determined in Step 4 to the uncertainty of the average you computed in Step 3. F. Calculate the % Error of your average value to the accepted value. G. Determine the statistical validity of this experiment. Experimental Actuall Experimental Uncertainty G. Put your data into a scatter plot in Excel, putting cm on the y-axis and in on the x- axis. Be sure to set the intercept at 0 and display the trendline equation on the graph H. Calculate the % Error of your slope to the accepted value. L Draw conclusions from your experiment and associated analysis. Discuss several possible sources of uncertainty in the measurements.
