Objective: The objective of this experiment was to find out why the moon “shrinks” as it goes from its rising point on the horizon to its highest point in the night sky. The way I decided to test this was by standing in the same spot periodically throughout the night and had a ruler in my hand. I fully extended my arm so that I knew it was in the same spot in relation to my line of sight and then proceeded to measure the moon. I began my observations as the moon rose in the sky and after every

A recent report on the weekly news presented the findings of a study on the effectiveness of Onglyza‚ along with diet and exercise‚ for treating diabetes. my answer: The implied population is all the people who are diabetics. Diabetics were used to test the effectiveness of Onglyza‚ diet and exercise. 2. In the following scenario identify the type of statistical study that was conducted.

hygrometer UK /haɪˈɡrɒmɪtər/ is an instrument used for measuring the moisture content in the atmosphere. Humidity measurement instruments usually rely on measurements of some other quantity such as temperature‚ pressure‚ mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation‚ these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation (the dew point)‚ or changes in electrical capacitance

discuss unemployment rate as a measure of economic performance. Another way to gauge economic performance is to count the number of jobs or number of people employed in the economy. Discuss the differences between these two measurements of job creation. Is either measurement better than the other? - The unemployment rate measures the number of workers who are at least 16 years old‚ who are not working and who have been trying to find a job within the past four weeks and still haven’t found one

considering the key control is measurement. However there are factors that affect efficacy in any building: percentage of minority students‚ average socioeconomic status‚ size‚ and average level of academic achievement. Group and single-subject designs have distinct strengths and limitations. Strategies include answering classroom-based research questions. There are across the board issues that are common to both‚ as to any research: research questions‚ replication and measurement‚ implementing and measuring

well as Pythagorean Theorem; so what about astronomy? Astronomers have a totally different format of information of which they are studying. It only makes sense that the astronomers would have a totally different way of which they measure. Two measurements astronomers use are triangulation (also known in math) and standard candles. Triangulation by technical terms is the method of determining distance based on the principles of geometry. Any type of math and science are closely related the principles

made an important distinction between measuring performance and managing performance (Verbeeten‚ 2008‚ p431). Performance measurement is one aspect of performance management‚ it is the regular collection and reporting of data to track work produced and results achieved therefore informs performance management (Lichello‚ p9). Performance managing entails using performance measurement as a management tool to clarify goals‚ the contribution toward achieving those goals‚ and understand the benefits received

Drilling Mud density or specific gravity is the most significant measurement required and no reliable visual estimate exists. The mud density or specific gravity must be accurately measured in order to successfully drill a well hole. The most accurate measurement of mud density is made by using the Mud Balance. Viscosity is the resistance to flow offered by a fluid. The term is loosely applied as the flow properties of drilling mud. The relative viscosity‚ or the cuttings carrying ability of the

William H. DeLone and Ephraim R. McLean Dependent variables are needed to be well defined in the IS success examination. Prior research more concerns on independent variables than the dependent variable. Instead‚ this article focuses on the measurement of the dependent variable. Shannon and Weaver (1949) and Mason (1978) yield six distinct categories or aspects of information systems success‚ which are system quality‚ information quality‚ use‚ user satisfaction‚ individual impact‚ and organizational

Experiment: Calorimetry Laboratory Experiment – Heat of Solution Aim: The aim was to use calorimetric measurements to calculate the molar heat of solution of NaOH and NH4NO3. Method: 1. 50g of water was poured into a clean polystyrene calorimeter (Styrofoam cup) and the initial temperature was measured. 2. A teaspoon of 2g of the selected salt was measured and added into the water. 3. The solution was stirred and the final temperature was measured when the solution stabilised and the results
