During the case, Liebeck's attorneys discovered that McDonald's required franchisees to hold coffee at 180–190 °F (82–88 °C). Liebeck's attorneys argued that coffee should never be served hotter than 140 °F (60 °C), and that a number of other establishments served coffee at a substantially lower temperature than McDonald's.
Designed experiments with full factorial design (left), response surface with second-degree polynomial (right) In statistics, a full factorial experiment is an experiment whose design consists of two or more factors, each with discrete possible values or "levels", and whose experimental units take on all possible combinations of these levels across all such factors.
The use of a sequence of experiments, where the design of each may depend on the results of previous experiments, including the possible decision to stop experimenting, is within the scope of sequential analysis, a field that was pioneered [12] by Abraham Wald in the context of sequential tests of statistical hypotheses.

A research design is an arrangement of conditions or collection. [5] Descriptive (e.g., case-study, naturalistic observation, survey) Correlational (e.g., case-control study, observational study) Experimental (e.g., field experiment, controlled experiment, quasi-experiment) Review (literature review, systematic review) Meta-analytic (meta-analysis)
Experimental data in science and engineering is data produced by a measurement, test method, experimental design or quasi-experimental design. In clinical research any data produced are the result of a clinical trial. Experimental data may be qualitative or quantitative, each being appropriate for different investigations.
A case study is an in-depth, detailed examination of a particular case (or cases) within a real-world context. [1] [2] For example, case studies in medicine may focus on an individual patient or ailment; case studies in business might cover a particular firm's strategy or a broader market; similarly, case studies in politics can range from a narrow happening over time like the operations of a ...
Known studies have published high scores for validity and reliability from small to large size sample sizes. In practice, it is customary to add additional items such as the respondent's demographics, prior experience with the brand or category and behavioural intentions (intention to revisit/ repurchase, loyalty intentions and propensity to ...
Molecular gastronomy includes the study of how different cooking temperatures affect eggs, [1] [2] their viscosity, surface tension, and different ways of introducing air into them. [3] Spherification of juices and other liquids is a technique of molecular gastronomy. A molecular gastronomy rendition of eggs Benedict served by wd~50 in New York ...
