2. Experiment (probability theory) - Wikipedia

   en.wikipedia.org/wiki/Experiment_(probability...

   A random experiment is described or modeled by a mathematical construct known as a probability space. A probability space is constructed and defined with a specific kind of experiment or trial in mind. A mathematical description of an experiment consists of three parts: A sample space, Ω (or S), which is the set of all possible outcomes.

3. Blocking (statistics) - Wikipedia

   en.wikipedia.org/wiki/Blocking_(statistics)

   In the examples listed above, a nuisance variable is a variable that is not the primary focus of the study but can affect the outcomes of the experiment. [3] They are considered potential sources of variability that, if not controlled or accounted for, may confound the interpretation between the independent and dependent variables .

4. Design of experiments - Wikipedia

   en.wikipedia.org/wiki/Design_of_experiments

   This example of design experiments is attributed to Harold Hotelling, building on examples from Frank Yates. [22] [23] [15] The experiments designed in this example involve combinatorial designs. [24] Weights of eight objects are measured using a pan balance and set of standard weights. Each weighing measures the weight difference between ...

5. Mathematical model - Wikipedia

   en.wikipedia.org/wiki/Mathematical_model

   Variables may be of many types; real or integer numbers, Boolean values or strings, for example. The variables represent some properties of the system, for example, the measured system outputs often in the form of signals, timing data, counters, and event occurrence. The actual model is the set of functions that describe the relations between ...

6. Experimental mathematics - Wikipedia

   en.wikipedia.org/wiki/Experimental_mathematics

   Mathematicians have always practiced experimental mathematics. Existing records of early mathematics, such as Babylonian mathematics, typically consist of lists of numerical examples illustrating algebraic identities. However, modern mathematics, beginning in the 17th century, developed a tradition of publishing results in a final, formal and ...

7. Replication (statistics) - Wikipedia

   en.wikipedia.org/wiki/Replication_(statistics)

   In engineering, science, and statistics, replication is the process of repeating a study or experiment under the same or similar conditions. It is a crucial step to test the original claim and confirm or reject the accuracy of results as well as for identifying and correcting the flaws in the original experiment. [1]

8. Statistical model - Wikipedia

   en.wikipedia.org/wiki/Statistical_model

   As another example, suppose that the data consists of points (x, y) that we assume are distributed according to a straight line with i.i.d. Gaussian residuals (with zero mean): this leads to the same statistical model as was used in the example with children's heights. The dimension of the statistical model is 3: the intercept of the line, the ...

9. Newcomb's paradox - Wikipedia

   en.wikipedia.org/wiki/Newcomb's_paradox

   In philosophy and mathematics, Newcomb's paradox, also known as Newcomb's problem, is a thought experiment involving a game between two players, one of whom is able to predict the future. Newcomb's paradox was created by William Newcomb of the University of California 's Lawrence Livermore Laboratory .
