  2. Inference - Wikipedia

    en.wikipedia.org/wiki/Inference

    Definition. The process by which a conclusion is inferred from multiple observations is called inductive reasoning. The conclusion may be correct or incorrect, or correct to within a certain degree of accuracy, or correct in certain situations. Conclusions inferred from multiple observations may be tested by additional observations.

  3. Deductive reasoning - Wikipedia

    en.wikipedia.org/wiki/Deductive_reasoning

    Deductive reasoning. Deductive reasoning is the process of drawing valid inferences. An inference is valid if its conclusion follows logically from its premises, meaning that it is impossible for the premises to be true and the conclusion to be false. For example, the inference from the premises "all men are mortal" and " Socrates is a man" to ...

  4. Abductive reasoning - Wikipedia

    en.wikipedia.org/wiki/Abductive_reasoning

    A Mastermind player uses abduction to infer the secret colors (top) from summaries (bottom left) of discrepancies in their guesses (bottom right).. Abductive reasoning (also called abduction, [1] abductive inference, [1] or retroduction [2]) is a form of logical inference that seeks the simplest and most likely conclusion from a set of observations.

  5. Statistical assumption - Wikipedia

    en.wikipedia.org/wiki/Statistical_assumption

    Design-based assumptions. These relate to the way observations have been gathered, and often involve an assumption of randomization during sampling. [6] [7] The model-based approach is the most commonly used in statistical inference; the design-based approach is used mainly with survey sampling. With the model-based approach, all the ...

  7. Statistical inference - Wikipedia

    en.wikipedia.org/wiki/Statistical_inference

    t. e. Statistical inference is the process of using data analysis to infer properties of an underlying distribution of probability. [ 1 ]Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates. It is assumed that the observed data set is sampled from a larger population.

  8. Scientific method - Wikipedia

    en.wikipedia.org/wiki/Scientific_method

    e. The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.

  9. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    Sample size determination or estimation is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample. In practice, the sample size used in a study is usually determined ...
