Precision can have different meanings, depending on what level of variability is included.. measurement is much more precise than the original estimate, how do you know that it is accurate, and how confident are you that this measurement represents the true value of the ring’s mass? Be sure to record your measured masses on your lab report. Weighing by Difference Download. 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. Objectives: Follow the lab report guidelines and don't forget that this must be in complete sentences in a paragraph. Precision and Accuracy Lab Report Topics: Measurement , Accuracy and precision , Density Pages: 4 (991 words) Published: February 22, 2012 Surveying Lab Report 1.

My data table 01.07 Accuracy and Precision: Balance Lab Worksheet Mrs. Estevens Part I: Density of Unknown Liquid 1. ... that the relative precision computed—38—is not within the 1 1 range of accepted precision for measuring distance by pacing, which is from 200 to500. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) However, you may use your lab manual, graded lab reports, notes, and textbook as resources for this exam. 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. Then, that water was poured into the pre-weighed beaker and put on the scale. In this video, I define Precision and Accuracy and use examples to illustrate the differences between them.

Once the measurement was recorded, the beaker and burette were both cleaned and dried. Once the lab exam begins, you are not permitted to receive any assistance from your TA or other students. 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. How would we know the precision of our measurement. Calculate the mass of the liquid for each trial. CHM Lab 2: Accuracy and Precision Accuracy and Precision And Jesus said, “Yes, the very hairs of your head are all numbered! Planning experiments and investigations.

This process was repeated two more times. 44 EXPERIMENT 4: ACCURACY & PRECISION IN MEASUREMENT Procedure: Before arriving to the lab, remember to prepare all the data tables in your lab notebook. This paper. Comparing the Precision of two types of Balances. Accuracy and Precision: Accuracy refers to the closeness of a measured value to a standard or known value. Though you can handle them, they are somewhat complex. For this data, this will be 12.4±1.14. DOCX. Samples of these tables have been provided as a guide. PDF. Premium PDF Package. When reading non-electronic devices such as rulers, thermometers, and glassware, the general rule of thumb is to "read between the lines"! 19 Full PDFs related to this paper. Using this calculation, the precision of the scale can be represented by giving the mean, plus or minus the standard deviation. PDF. Outline The standard deviation is perhaps the most common measurement of precision. Download Free PDF. Trial # 2. Hypothesis GOAL! Lab report templates are documents which are written to explain, describe and analyze a laboratory experiment. Obtain a 250-mL Erlenmeyer flask from your locker. 16. Surveying Lab Report 1. Record your data directly in your lab notebook. Measurement is an important skill used for data collection and data analysis. Using these uncertainties we can find out whether our measurements were accurate, precise, and realistic. Related Studylists. 1. [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 . Meanwhile, the beaker ended up being the least accurate and precise.

Make measurements to the nearest 1/10 of a millimeter using a meter stick. 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. 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. Use the electronic balance in the weigh room to determine the mass of the same Erlenmeyer flask.
