Educated guess

The scientific method is taught starting in elementary school. The first step in the scientific method is to form a hypothesis. A hypothesis is just an educated guess or logical conclusion from known facts. It is then compared against all available data and its details developed. If the hypothesis is found to be consistent with known facts, it is called a theory and usually published. The characteristics most theories have in common are that they explain observed phenomena, predict the results of future experiments, and can be presented in mathematical form. When a theory is found to be always correct for many years, it is eventually referred to as a scientific law. However useful this process is, we often use constructs that do not fit in the scientific method scheme as it is typically described. [Pg.2]

It will be apparent from the discussions in the previous sections that an absolute value of reliability is at best an educated guess. However, the risk of failure determined is a quantitative measure in terms of safety and reliability by which various parts can be defined and compared (Freudenthal et al., 1966). In developing a reliable product, a number of design schemes should be generated to explore each for their... [Pg.202]

When the incidence of occupational diseases was compared with the frequency of OEL violations in Finland, a rather good correlation was observed. This indicates that these OELs are reasonably well defined. This is also natural because they are based on long-term exposure history of a large number of people. However, the OELs for many chemicals are still only educated guesses, and numerous and often large changes have been made when the OEL lists have been revised. In addition, most chemicals still have no OEL. Only about 2000 chemicals have an OEL in some country. ... [Pg.240]

The crowd inside could have been a reunion party for a batch of genetic clones, Class of 93. Everybody was exactly twenty-nine, to an educated guess. Most were drinking Corona beer from bottles. [Pg.36]

Prediction, as well as analysis, is also important. Conceptually, the difference is clear, but it is seldom properly appreciated. Risk is associated with predictions, but there should not be any significant risk associated with an analysis. To put it rather simply Prediction is about making informed, educated guesses about uncertain, untested events, whereas analysis is about... [Pg.124]

Hard evidence for the first category seems to be nonexistent. An educated guess on the potential hazards would combine residue technology [how much of a secondary amine (or amide, urea, carbamate, etc.) might a person consume or otherwise be exposed to ], nitrosation chemistry (what would be the yield of in vivo nitrosation of the pesticide thus consumed ), and toxicology (what would be the toxicological effect and potency of the nitroso compound thus formed ). Frequently, these questions, which simplify to, "What dose—eg., in mg/kg—of a pesticide-derived nitroso compound might a person be exposed to and what would be the result if he were " are not carefully considered. [Pg.350]

Train and test a network with a certain number of hidden units, based on an educated guess. When the NSE of the network is acceptable and no severe overtraining occurs, the network is suitable. [Pg.678]

Do bear in mind that most of this is an educated guess and I may not be... [Pg.79]

The two steps just discussed require that one or more responses be constrained, and a question may arise as to which ones to select. The formulator may have certain basic constraints, such as a minimum hardness value, but it is nevertheless important to know which property or properties can be used to distinguish between the available choices. Generally, this is done by an educated guess, based on experience with the system and with pharmaceutical systems in general. [Pg.617]

Three types of design problems fit this situation. One is the design of a plant for a totally new product. The second is the design of a new process for a product that currently is being produced. The last is the preliminary design of a competitor s plant, to determine what his costs are. In each of these, little is known about the process, so that a large amount of educated guessing must occur. [Pg.495]

If you do not know the field range occupied by your spectrum in advance, the center field must be chosen by educated guess set the sweep width 2-4 x greater than the expected width. Hopefully, you will see at least a piece of your spectrum and can make appropriate adjustments to zero in on the correct settings. [Pg.13]

It is clear, however, that in complex situations it is not possible to make an educated guess of the biasing potential. In particular the position of the transition regions... [Pg.120]

If you can eliminate one or more of the answers in a multiple-choice question, make an educated guess. [Pg.399]

The words, phrases, and sentences surrounding an unfamiliar word. The context can help you make an educated guess about a new word or phrase. [Pg.13]

The length of time required for recovery of LNAPL products is based on the volume of product present in the subsurface and is limited by numerous factors. Most often based on an educated guess, factors regarding volume estimates have innate compounding errors in relation to ... [Pg.200]

Did you make an educated guess An educated guess might indicate that you have some familiarity with the subject, but you probably need at least a quick review. [Pg.18]

Proteins can be classed into groups based on their overall 3-D shapes, known as protein folds (O Figure 22-la). In general, proteins that have similar functions have similar folds. This means that if you are the proud parent of an unknown protein whose structure is solved, it may be possible to make educated guesses as to the function of the protein based on its overall fold. There are a number of well-known exceptions to this [notably, the serine protease family, subtilisin and trypsin/chymotrypsin (Hartley, 1979)], but the... [Pg.457]

Note that, to call attention to an important source of variability in the onset time, we used the term dose onset factor (Donset). As stated, it represents the decrease in Tonso, (the time at which NF performance first falls below 25% of baseline) when the incapacitating dose (IDso) is doubled. In the case of BZ, for example, doubling the absorbed dose shortens the Tonso from four hours to less than an hour. Doubling it again presumably shortens it to just a few minutes. This would be an important concept for military plarmers to consider. Our data were insufficient to measure the Domet precisely because we preferred not to administer double doses to volunteers, hr the few cases in which actual aerosol doses were considerably higher than the intended value, however, the dramatically earlier onset of incapacitation allowed an educated guess of the Donset. [Pg.275]
