Having a profit center measurement approach for infrastructure that operates in a cost center approach‚ will not provide reasonable measurements for the management control system. The plant manager’s concern regarding the evaluation system is valid. Without proper control over the input and output you cannot expect the plant manager

net/tutorial/Colosi/lcolosi2.htm Reliability and Validity: What’s the Difference? Reliability Definition: Reliability is the consistency of your measurement‚ or the degree to which an instrument measures the same way each time it is used under the same condition with the same subjects. In short‚ it is the repeatability of your measurement. A measure is considered reliable if a person’s score on the same test given twice is similar. It is important to remember that reliability is not measured

change due to the length of wire. The length of wire will be measured accurately using a metre rule. The wire will be stuck onto the rule using tape. This means that the wire will not move about so we can measure the length accurately. Repeating measurements improve accuracy as you can spot any anomalies and the results can be averaged to give more reliable results. The voltmeter will give the reading for voltage ( V ) and the ammeter will give the reading for current ( I ). The resistance will then

Hess’ Law. Heat may increase during experiment and undergo exothermic reaction. Analysis: Q = m c (Tf - Ti) = 27.9°C – 21.3°C = 6.6°C Q = (101.81g)(4180kJ/g°C)(6.6°C) Q = 2808734 kJ Discussion: Measurements were relatively accurate and closely linked to quantitative values. When measurement was a little higher‚ value resulted a little higher. The Styrofoam for this experiment was necessary because it insulates leading to less energy loss to the surrounding of the system. Because there was

examining the Values and Motives Inventory (VMI) are the issues that encompass the reliability and validity of this instrument. Reliability not only examines the dependability of scores‚ but also measures and accounts for the standard error of measurement (SEM) within the instrument (Whiston‚ 2009). The SEM is a hypothesis of what the scores would be if one took the test more than once (Whiston‚ 2009). Validity is when the test actually “measures what it claims to measure” (Values and Motives Questionnaire

(Hoff‚ Wisloff‚ Engen‚ Helgerud‚ 2002‚ p.219) 2. Measurements: For the warm up VO2 was measured by placing the subjects on a treadmill with 3 degree incline for 20 minutes. The speed of the treadmill increased 1km/h every minute until VO2 max was met. After VO2 max was reached the subjects were required to

Theory The HSE want the assessing of health and safety performance to be of equivalent importance to the measurement of financial‚ production or service delivery management. HSE ask companies to follow the HSG 65 procedure (fig1). This diagram highlights where the evaluating and reviewing fits in the overall health and safety management system
