This document describes a general format for lab reports that you can adapt as needed. Worse yet, each professor wants something a little different. Regardless of variations, however, the goal of lab reports remains the same: document your findings and communicate their significance.

An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale, but always rely on repeatable procedure and logical analysis of the results.

Design of Experiments (DOE)

Published on December 3, by Rebecca Bevans. Revised on March 8, An experiment is a type of research method in which you manipulate one or more independent variables and measure their effect on one or more dependent variables. Experimental design means creating a set of procedures to test a hypothesis. A good experimental design requires a strong understanding of the system you are studying. By first considering the variables and how they are related Step 1 , you can make predictions that are specific and testable Step 2.

Experimental research is the most familiar type of research design for individuals in the physical sciences and a host of other fields. This is mainly because experimental research is a classical scientific experiment, similar to those performed in high school science classes. Imagine taking 2 samples of the same plant and exposing one of them to sunlight, while the other is kept away from sunlight. Let the plant exposed to sunlight be called sample A, while the latter is called sample B. If after the duration of the research, we find out that sample A grows and sample B dies, even though they are both regularly wetted and given the same treatment.

The term experiment is defined as the systematic procedure carried out under controlled conditions in order to discover an unknown effect, to test or establish a hypothesis, or to illustrate a known effect. When analyzing a process, experiments are often used to evaluate which process inputs have a significant impact on the process output, and what the target level of those inputs should be to achieve a desired result output. Experiments can be designed in many different ways to collect this information. Experimental design can be used at the point of greatest leverage to reduce design costs by speeding up the design process, reducing late engineering design changes, and reducing product material and labor complexity. Designed Experiments are also powerful tools to achieve manufacturing cost savings by minimizing process variation and reducing rework, scrap, and the need for inspection.

A guide to experimental design

The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century. It involves careful observation , applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses , via induction , based on such observations; experimental and measurement-based testing of deductions drawn from the hypotheses; and refinement or elimination of the hypotheses based on the experimental findings. These are principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises. Though diverse models for the scientific method are available, there is in general a continuous process that includes observations about the natural world. People are naturally inquisitive, so they often come up with questions about things they see or hear, and they often develop ideas or hypotheses about why things are the way they are. The best hypotheses lead to predictions that can be tested in various ways.

Control group , the standard to which comparisons are made in an experiment. Many experiments are designed to include a control group and one or more experimental groups; in fact, some scholars reserve the term experiment for study designs that include a control group. Ideally, the control group and the experimental groups are identical in every way except that the experimental groups are subjected to treatments or interventions believed to have an effect on the outcome of interest while the control group is not. Indeed, only in the presence of a control group can a researcher determine whether a treatment under investigation truly has a significant effect on an experimental group, and the possibility of making an erroneous conclusion is reduced.

Стратмор отсутствующе смотрел на стену. - Коммандер. Выключите .

 Слишком поздно, - сказал Стратмор. Он глубоко вздохнул.  - Сегодня утром Энсея Танкадо нашли мертвым в городе Севилья, в Испании. ГЛАВА 8 Двухмоторный Лирджет-60 коснулся раскаленной посадочной полосы. Голый ландшафт испанской нижней Эстремадуры бежал за окном, слившись в неразличимый фон, затем замедлил свой бег.

The Lab Report

Ну что еще? - застонал.  - Хочет предъявить мне обвинение во вторжении в личную жизнь. Девушка волокла за собой туристскую сумку. Подойдя к нему, она на этот раз расплылась в широкой улыбке. - Простите, что я на вас накричала. Я так испугалась, увидев .

Сьюзан нахмурилась. Она понимала, что найти принадлежащую Хейлу копию ключа будет очень трудно. Найти ее на одном из жестких дисков - все равно что отыскать носок в спальне размером со штат Техас. Компьютерные поисковые системы работают, только если вы знаете, что ищете; этот пароль - некая неопределенность.

 Что. - Деление на ноль, - сказала она, пробегая глазами остальные данные.  - Средняя цена определяется как дробь - общая стоимость, деленная на число расшифровок. - Конечно.  - Бринкерхофф рассеянно кивнул, стараясь не смотреть на лиф ее платья. - Когда знаменатель равняется нулю, - объясняла Мидж, - результат уходит в бесконечность.

 - Значит, тебе известно про Цифровую крепость. А я-то думал, что ты будешь это отрицать. - Подите к черту.

 Не может быть, чтобы Грег Хейл был гарантом затеи Танкадо. Это полный абсурд. Танкадо ни за что не доверился бы Хейлу.

Я вам все верну. Беккер подумал, что деньги, которые он ей даст, в конечном счете окажутся в кармане какого-нибудь наркоторговца из Трианы. - Я вовсе не так богат, я простой преподаватель.

 - Взгляни-ка на. Прочитав написанное, Сьюзан поняла ход мысли коммандера. На бумажке был электронный адрес Северной Дакоты.

Он оказался в узком, увешанном зеркалами туннеле, который вел на открытую террасу, уставленную столами и стульями. На террасе тоже было полно панков, но Беккеру она показалась чем-то вроде Шангри-Ла: ночное летнее небо над головой, тихие волны долетающей из зала музыки. Не обращая внимания на устремленные на него любопытные взгляды десятков пар глаз, Беккер шагнул в толпу.

 - Давай я тебе помогу. - Ах ты, пакостник. - Не знаю, что ты такое подумала. - Я рада, что поймала тебя, - продолжала.  - Мне нужен совет.

Стратмор провел рукой по вспотевшему лбу.
