ball was measured and recorded by the class. These measurements were to determine error in measurements and the derived quantities‚ volume and density. The diameter was determined using a dial caliper and the mass‚ a triple beam balance. The results of the error for diameter were not as expected while the results of the volume and density were deviated greatly from expectations; only the weight had a small error.

Gerong Department of Math and Physics College of Science‚ University of Santo Tomas España‚ Manila Abstract Measurements‚ defined as a comparison with a standard‚ are essential in the study of physics. However‚ all measurements are prone to errors. There are two sources of errors: systematic errors random errors. This experiment

Experiment 1: Errors‚ Uncertainties and Measurements Laboratory Report Abstract The success of an experiment greatly depends on how the group is able to execute it and how precise and accurate their results are. In this matter‚ errors and uncertainties in measurements are of great factor. In this experiment‚ the group was able to classify the causes of such errors and which measuring device is more precise and accurate than the other. These were obtained by measuring the diameter of an iron sphere

all subject to error which leads to the uncertainty of the result. Errors may come from systematic errors (deterministic error) or random error (not deterministic error). In this experiment‚ the group measured the diameter of sphere using different kinds of measuring devices (foot rule‚ vernier caliper‚ and micrometer caliper) in order to achieve accuracy in the scientific measurements. After experimenting‚ it was revealed that the micrometer caliper has the lowest percentage of error. 1. Introduction

Basic Concepts of Error Analysis 1. Significant Figures: The laboratory usually involves measurements of several physical quantities such as length‚ mass‚ time‚ voltage and current. The values of these quantities should be presented in terms of Significant Figures as follows. For example‚ the location of the arrow is to be determined in Fig. 1. It is obvious that the location is between 1 cm and 2 cm. The correct way to express this location is to make one more estimate based on your intuition

Errors and Uncertainty in Experimental Data Causes and Types of Errors Conducting research in any science course is dependent upon obtaining measurements. No measure is ever exact due to errors in instrumentation and measuring skills. If you were to obtain the mass of an object with a digital balance‚ the reading gives you a measure with a specific set of values. We can assume that the actual measure lies either slightly above or slightly below that reading. The range is the uncertainly of
