bars, both directions and the error amount to be a custom range. Put in the cells thatcontain the standard deviation of your absorbencies into the + and - custom fields. Below is a representative external calibration with y-error bars representing the 2
standard deviation in the pooled class data. Remember, the linear function should beused to describe only the linear portion of the graph. Do not include non-linear data points in your curve. Format the axes and trend line data to the appropriate number of significant figures.05101520253035404550556065707580859095 100 1050.00000.50001.00001.50002.00002.50003.0000f(x) = 0.03xR² = 0.99Corrected AvgConcentrationAverage Absorbance3.Plot the data again and provide the graph, this time showing all of the raw data instead of averaging the replicates into one point. To do this you will need all of the data in single (x,y) data matrix. Please ask your instructor if you need help. Using this method, you will not have error bars. 3

How about the linear equation?
How does averaging change the results on the calibration?
4.Fully describe and calculate the figures of merit for the calibration. Calculate the LoD: In order to solve for the Limit of Detection you have to use 3 times standard deviation divided by the slope. The calculated limit of detection are
