Question

Partner's Name Table 2. Calculated Data- Mean, standard deviation, and percent errors for volumes Fill in the table with the values calculated using Excel. Calculated Value Actual volume Mean Standard Deviation Percent Error Beaker Graduated cylinder Volumetric lask Buret Pipet 2245 m Show correct significant figures and units for all data that require units for full credit. Attach your Excel spreadsheet used to find volume means and standard deviations. A sample spreadsheet with fictitious data is shown in Figure 1 of the Data Analysis section. Show below sample calculations using beaker data. Calculate the "actual volume" for your first trial using beaker data in Table 1, and then calculate the "percent error" for the volume using the mean of all eight measurements for beaker data in Table 2. 1. Calculation of actual volume of your first 25 mL sample using the beaker. 2. Calculation of percent error in measuring 25 mL using a 100 ml or 150 mL beaker. %error 21.391 25.)13% Rev 8-23-17 12
