Greats Sample Lab Report F Lab 3 Measurements And Uncertainty lab 3 measurements and uncertainty accepted value of 7 8 10 3 kg m 3 Using these uncertainties we can find out whether our measurements were accurate precise and realistic In our trials we found the average diameter of the ball to be 1 81 cm and the uncertainty in the diameter was 01cm using the vernier caliper We took the average value because our measurements were random lab 3 measurements and uncertainty Lab 1 Measurement and Uncertainty measurements will be within 1 f of the mean and 95 within 2 f Therefore when we use a single measurement as a guess for the mean value the uncertainty of that guess is just f the standard deviation 2 If we take repeated measurements the best guess we can make for the true value is the average mean of all the measurements LAB 2 Measurements and Error Analysis for this lab any measurements and calculations should be stated in the standard form of measurement xbest x Part I Using Measuring Devices Calculate the volume and uncertainty 3 Measure the mass with the triple beam balance 4 Calculate the density M V and uncertainty Measurement Analysis 1 Measurement Uncertainty and Measurement Analysis 1 Measurement Uncertainty and Propagation 1 2 Uncertainties in measurements in lab In the laboratory you will be taking real world measurements and for some measurements 1 3 Percentage uncertainty of measurements When we speak of a measurement we often want to know how reliable it is Uncertainty and error in lab measurements measurements are very close to this value but as with all measurements there is some uncertainty associated with them We can use a similar method called percent difference to compare two
