Measurement

measured with the zero on the ruler, so that students are at least introduced to the correct way of approaching measurement. However, it is important to focus more on the underlying concept, and that will require students to actually be involved in creating a conceptual framework for measurement themselves (Swan, 2001). Averill and Harvey (2010) suggest introducing students to measurement through self-made scales rather than launching into using a ruler so that they can begin to grasp an…

In the field of economics, there are many measurements that attempt to quantify the economic wellbeing of an area. Many of which are used like a scorecard in order to try to improve upon itself. However, these measurements, as well as they quantify variable data, they are not without their shortcoming on how they gather their data. Indicators such as unemployment rate, inflation and GDP are vulnerable to misrepresenting the economic climate through issues revolving around how their information…

J. Connolly et.al [28] also propose a wearable rehab technology for automatic measurement of patients with arthritis. They put forward the ideas surrounding the development of an accurate hand measuring tool to assist medical clinicians and rheumatologists in the accurate measurement of finger and thumb movement of the human hand. Angle measuring instruments, tape measure and grip strength dynamometer are used to assess the joint range and function of a patient to determine their hand function.…

and blew through the end that was capped by the finger. The free floating bubbles were allowed to descend to the ground where their diameter was measured by a ruler. We found the averages by adding both the measurements of each solution in each test and dividing them by the number of measurements, two. For example: 1.25+1.30+1.20=3.75/3=1.25 average. There were multiple steps taken to prepare our data taken for analysis. Throughout our study, we took observations on the solutions and their…

other measuring tools.In this lab, we measured water from pipettes including volumetric and graduated pipettes, graduated cylinders, erlenmeyer flasks, and beakers to figure out the mass and density. These measurements were then used to calculate the percent error. We completed these measurements by measuring the volume of the pipettes in milliliters, the initial mass of the beaker without water in grams, and the final mass of the beaker with water in grams. We did this procedure again, and also…

11a, lab 1: Motion, Measurement and Statistics In the first lab we will investigate the motion of a ball rolling down an inclined plane. We will use this simple system to investigate the concept of systematic and random measurement uncertainties to understand how much we can trust a measurement. We will then compare the experimental outcome with theory. I. Ball on an inclined plane: Measuring motion We want to measure the motion of a ball that rolls down on an inclined plane…

that the findings from these surveys are based on survey estimates, because of this, the results are subject to scrutiny and uncertainty. This means rather than having the exact measurement of well-being in the United Kingdom (UK), the results should be interpreted as providing a good estimate and not as an exact measurement. The advantage of measuring well-being inequality is that you can compare the differences of well-being compared to their income between higher and lower socio-economic…

A system called CWEED, which measures energy in Ontario and it can "provides solar global measurements as the total of direct and diffuse radiant energy received by a pyranometer." (Hoicka, Rowlands,2011). Therefore, an efficient system can determine whether citizens have easy access to reliable energy or not. However, in some developing countries…

Prior to field measurements (during the identification field experience), practice cover estimates were recorded randomly on the site to ensure consistency. Percentage of canopy density was measured using a convex spherical forest densiometer, instrument design to estimate…

Aim The aim of this practical is to measure the effect of volume, density and temperature. It is also help to be familiar with variety of common laboratory technique. Materials Weighting scale Container with lids 20 and 10 ml Volumetric pipette Beaker Thermometer Test Tubes Volumetric flask Natural Rubber Pipette Filler Micropipette tips Tips boxes Method There are two pipette, choose one which you using in whole practical. Label and weight accurately, to 4 decimal places. Collect…
