Lab 1- Measurements of a Table ABSTRACT: The purpose of this experiment was to determine the value of the acceleration of a free falling object and to describe the range of experimental values. Within the experiment the items used to help provide the conclusion that 2/3 or our values fell within the 9.62m/s^2- 9.78m/s^2 range was a Vernier data-collection interface‚ Logger Pro Application and the apparatus Photogate. The results found within the 30 trial periods were all precise

Preliminary Experiment At first in our preliminary experiment my group and me decided to use an ohmmeter instead of a multimeter. We did this as we thought it would make it easier for us to record our results. These are the results we got from our preliminary experiment: Length (mm)

Abstract- Expirement 1: Precision‚ Accuracy‚ and Density Measurements This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well‚ to determine the mass‚ volume and density of water by using various types of measuring glasswear‚ such as beakers‚ graduated cylinder‚ pipet‚ etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also‚ there will be a

Lab Report 1: Measurement Lab Date: January 17‚20XX Lab Partners: XZ Report Date: January 24‚2014 Report Written by: XXXXXX Introduction: Measurement is a form of quantitative observation. The ability to make accurate and precise quantitative observations is crucial to science. Accuracy in this sense refers to the closeness of the measured result to the hypothetical “true” value (Motzny 2014). Having a precise measurement implies its exactness.

ARCELIA ARRATIA MEASUREMENT OF LENGTH‚ MASS‚ VOLUME‚ AND DENSITY PHYSICS LAB REPORT Physics is the scientific study of matter and energy and how they interact with each other. Physics utilizes the scientific formula to test hypothesis and calculate matter such as density. Tools were created to measure material in a laboratory and have been perfected to reduce error. In this experiment measurement of length‚ mass‚ volume and density will be obtained through instruments of measuring

then computing with them. This type of data is either nominal or ordinal. Nominal The number we assign to some object‚ idea‚ or behavior is entirely arbitrary‚ although in some cases a tradition may establish the rules of assignment. If measurements are assigned arbitrary numbers‚ they are called nominal numbers‚ and their sole purpose in the analysis is to differentiate an item possessing one characteristic from an item possessing a different characteristic. Nominal data is a type of categorical

Question Think of a class you’ve taken in the past. What standards of performance did your lecturer establish? How was your actual performance measured? Do you think the standards and methods and measurements were fair? 1 Introduction When the authors flash back on the days when they were very naive and very fresh from their foundation class‚ they actually laughed at themselves. The authors were so scared at the first time because this is the first time they are experiencing college life when
