Hypothesis GOAL! Then, that water was poured into the pre-weighed beaker and put on the scale. Understand that the level of accuracy is linked to the context. Be sure to record your measured masses on your lab report. Objectives: Follow the lab report guidelines and don't forget that this must be in complete sentences in a paragraph. Since the digital display of the balance is limited to 2 decimal places, you could report … [2] [3] Although the two words precision and accuracy can be synonymous in colloquial use, they are deliberately contrasted in the context of the scientific method . PDF. Introduction. Use the electronic balance in the weigh room to determine the mass of the same Erlenmeyer flask. This lab helped us learn how to make measurements using a caliper and how to use measurement uncertainties to find the density of the steel ball and compare it with the accepted value of 7.8*10^3 kg/m^3.

A measurement reading usually has one more significant figure than the least c ount reading of ... that the strip is closer to 41.6 cm than it is to 41.7 cm and report the length to be 41.64 cm or 0.4164 m. 2 Triple-beam balance. Precision can have different meanings, depending on what level of variability is included.. Download. In our trials we found the Lab 2 Measurements - Lab report. Once the lab exam begins, you are not permitted to receive any assistance from your TA or other students. A short summary of this paper. Current research interests are in on-machine measurement sensors and instrumentation for precision machine tools, robotic machine tools, or semiconductor machine tools applied to real-time manufacturing process monitoring, prognostics, diagnosis and preventive maintenance at a low-cost, convenient, accurate and precise manner. Procedure (1): Lab Table If the dimensions of the object being measured are much larger than the precision of the measuring instrument (100 times or more), the instrument is considered very adequate for the measurement and will give fairly "precise" results. Essay Example on Precision Measurement Lab Report. Record your data directly in your lab notebook. DOCX.

Fear not therefore; you are of more value than many sparrows”. Lab 1: Precision Measurements September 1, 2016 Objectives Experiment 1: Density of Metal Cylinders The Samples of these tables have been provided as a guide. Outline For this data, this will be 12.4±1.14. Electronic balance to your sample lab report precision measurement or cylinder and the value Prior to the different sample lab report precision measurement, the most accurate measuring device and more precise as possible and ensure that the vessel. Measurement is an important skill used for data collection and data analysis. PDF. Report your result. Use the triple-beam balance to determine the mass of this flask. The precision of a measurement is a measure of the reproducibility of a set of measurements. Free PDF. Download lab report templates & examples FREE Related Studylists. Precision and Uncertainties for Common Lab Equipment When you record a scientific measurement, the last digit that you record is understood to have some uncertainty, and to be your best estimate. Since you will be adding your own data to it, you may want to click on File Save As to allow you to rename and save a copy of the worksheet in the student data folder for your lab period. Third, a 25 ml burette was used to measure out 14 ml of water. Using a meter stick, measure the length and the width of the lab table and This may be neglected at the moment, though, as this ... HORIZONTAL DISTANCE MEASUREMENT. Planning experiments and investigations. 44 EXPERIMENT 4: ACCURACY & PRECISION IN MEASUREMENT Procedure: Before arriving to the lab, remember to prepare all the data tables in your lab notebook. DOCX. Evaluating data, considering anomalous results. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) PDF. Data/ Results (Continued) Data/ Results (Continued) Data/ Results Conclusion In conclusion, our hypothesis was proven correct by the results of the pipette being the most accurate and precise. Using this calculation, the precision of the scale can be represented by giving the mean, plus or minus the standard deviation. Measurement repeatability (s repeatability, s r) expresses the closeness of the results obtained with the same sample (or subsamples of the same sample) using the same measurement procedure, same operators, same measuring system, same operating conditions and same location over a short period of time. Measurement, accuracy and precision Teachers’ notes Objectives Understand that data obtained during experiments are subject to uncertainty. before you get to Lab. 1.0 ABSTRACT Viscosity is one of the properties to describe the “fluidity” of fluid. This process was repeated two more times. For example, if in lab you obtain a weight measurement of 3.2 kg for a given substance, but the actual or known weight is 10 kg, then your measurement is not accurate. Meanwhile, the beaker ended up being the least accurate and precise. Premium PDF Package.
