Evaluation
Evaluation is a systematic determination and assessment of a subject's merit, worth and significance, using criteria governed by a set of standards. It can assist an organization, program, design, project or any other intervention or initiative to assess any aim, realisable concept/proposal, or any alternative, to help in decision-making; or to ascertain the degree of achievement or value in regard to the aim and objectives and results of any such action that has been completed. The primary purpose of evaluation, in addition to gaining insight into prior or existing initiatives, is to enable reflection and assist in the identification of future change. Evaluation is often used to characterize and appraise subjects of interest in a wide range of human enterprises, including the arts, criminal justice, foundations, non-profit organizations, government, health care, and other human services. It is long term and done at the end of a period of time. Definition Evaluation is the stru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octane Rating
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the ...

Grade (education)
Grading in education is the process of applying standardized measurements for varying levels of achievements in a course. Grades can be assigned as letters (usually A through F), as a range (for example, 1 to 6), as a percentage, or as a number out of a possible total (often out of 100). In some countries, grades are averaged to create a grade point average (GPA). GPA is calculated by using the number of grade points a student earns in a given period of time. GPAs are often calculated for high school, undergraduate, and graduate students, and can be used by potential employers or educational institutions to assess and compare applicants. A cumulative grade point average (CGPA), sometimes referred to as just GPA, is a measure of performance for all of a student's courses. History Yale University historian George Wilson Pierson writes: "According to tradition the first grades issued at Yale (and possibly the first in the country) were given out in the year 1785, when Presiden ...

Rating System Of The Royal Navy
The rating system of the Royal Navy and its predecessors was used by the Royal Navy between the beginning of the 17th century and the middle of the 19th century to categorise sailing warships, initially classing them according to their assigned complement of men, and later according to the number of their carriage-mounted guns. The rating system of the Royal Navy formally came to an end in the late 19th century by declaration of the Admiralty. The main cause behind this declaration focused on new types of gun, the introduction of steam propulsion and the use of iron and steel armour which made rating ships by the number of guns obsolete. Origins and description The first movement towards a rating system may be seen in the 15th century and the first half of the 16th century, when the largest carracks in the Navy (such as the ''Mary Rose'', the ''Peter Pomegranate'' and the '' Henri Grâce à Dieu'') were denoted "great ships". This was only on the basis of their roughly-esti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health Care Ratings
Health care ratings are ratings or evaluations of health care. In the United States they have been an increasingly used tool to try to drive accountability among health care providers and in the context of classic supply/demand view of Health economics, to help health care consumers make better choices. Reviews in 2008 and 2009 review of research on the effects of health care ratings found that there was evidence that public ratings drove hospitals to improve their performance, but there was limited evidence that they affected how consumers choose health care providers or insurance plans, or that they changed the performance of individual doctors or insurance companies. In may cases it is difficult to create health care ratings that can meaningfully summarize any individual provider's performance in a way that be compared with others', and data is often lacking with which to generate ratings. People may have difficulty finding the ratings, especially if they are negative. To make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rating Site
A review site is a website on which reviews can be posted about people, businesses, products, or services. These sites may use Web 2.0 techniques to gather reviews from site users or may employ professional writers to author reviews on the topic of concern for the site. Early examples of review sites included ConsumerDemocracy.com, Complaints.com, planetfeedback.com, and Epinions.com. Business models Review sites are generally supported by advertising. Some business review sites may also allow businesses to pay for enhanced listings, which do not affect the reviews and ratings. Product review sites may be supported by providing affiliate links to the websites that sell the reviewed items, which pay the site on a per-click or per-sale basis. With the growing popularity of affiliate programs on the Internet, a new sort of review site has emerged: the affiliate product review site. This type of site is usually professionally designed and written to maximize conversions, and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rating (wine)
A wine rating is a score assigned by one or more wine critics to a wine tasted as a summary of that critic's evaluation of that wine. A wine rating is therefore a subjective quality score, typically of a numerical nature, given to a specific bottle of wine. In most cases, wine ratings are set by a single wine critic, but in some cases a rating is derived by input from several critics tasting the same wine at the same time. A number of different scales for wine ratings are in use. Also, the practices used to arrive at the rating can vary. Over the last couple of decades, the 50–100 scale introduced by Robert M. Parker, Jr. has become commonly used. This or numerically similar scales are used by publications such as ''Wine Enthusiast'', ''Wine Spectator'', and '' Wine Advocate''. Other publications or critics, such as Jancis Robinson and Michael Broadbent, may use a 0–20 scale, or a 0–5 scale (often in terms of numbers of stars) either with or without half-star steps.J.

Rating (clinical Trials)
Within the field of clinical trials, rating is the process by which a human evaluator subjectively judges the response of a patient to a medical treatment. The rating can include more than one treatment response. The accessor is normally an independent observer other than the patient, but the accessor can also be the patient (a patient-reported outcome). Furthermore, some clinical outcomes can only be assessed by the patient (a "private phenomena"). Because the evaluation is subjective, this can result in both inter-rater or intra-rater reliability. When conducting clinical trials, ensuring rating consistency is important, but can prove to be quite difficult to obtain. Studies dealing with such indications as pain, mental disease A mental disorder, also referred to as a mental illness or psychiatric disorder, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. Such features may be persistent, relapsing and remitti .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elo Rating System
The Elo rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess. It is named after its creator Arpad Elo, a Hungarian-American physics professor. The Elo system was invented as an improved chess-rating system over the previously used Harkness system, but is also used as a rating system in association football, American football, baseball, basketball, pool, table tennis, and various board games and esports. The difference in the ratings between two players serves as a predictor of the outcome of a match. Two players with equal ratings who play against each other are expected to score an equal number of wins. A player whose rating is 100 points greater than their opponent's is expected to score 64%; if the difference is 200 points, then the expected score for the stronger player is 76%. A player's Elo rating is represented by a number which may change depending on the outcome of rated games played. After every game, the winn ...
