  2. Mathematical statistics - Wikipedia

    en.wikipedia.org/wiki/Mathematical_statistics

    Statistical inference is the process of drawing conclusions from data that are subject to random variation, for example, observational errors or sampling variation. [8] Initial requirements of such a system of procedures for inference and induction are that the system should produce reasonable answers when applied to well-defined situations and ...

    en.wikipedia.org/wiki/Outline_of_scientific_method

    The problem of induction questions the logical basis of scientific statements. Inductive reasoning appears to lie at the core of the scientific method, yet also appears to be invalid. David Hume was the person who first pointed out the problem of induction. Karl Popper offered one solution, Falsifiability

    Whether it is justifiable to reject a hypothesis based on a low probability without knowing the probability of an alternative; Whether a hypothesis could ever be accepted based solely on data In mathematics, deduction proves, while counter-examples disprove. In the Popperian philosophy of science, progress is made when theories are disproven.

    The hypothesis of Andreas Cellarius, showing the planetary motions in eccentric and epicyclical orbits. A hypothesis (pl.: hypotheses) is a proposed explanation for a phenomenon. A scientific hypothesis must be based on observations and make a testable and reproducible prediction about reality, in a process beginning with an educated guess or ...

  6. Working hypothesis - Wikipedia

    en.wikipedia.org/wiki/Working_hypothesis

    Use of the phrase "working hypothesis" goes back to at least the 1850s. [7]Charles Sanders Peirce came to hold that an explanatory hypothesis is not only justifiable as a tentative conclusion by its plausibility (by which he meant its naturalness and economy of explanation), [8] but also justifiable as a starting point by the broader promise that the hypothesis holds for research.

    Heuer outlines the ACH process in considerable depth in his book, Psychology of Intelligence Analysis. [1] It consists of the following steps: Hypothesis – The first step of the process is to identify all potential hypotheses, preferably using a group of analysts with different perspectives to brainstorm the possibilities.

    en.wikipedia.org/wiki/Research_question

    A research question is "a question that a research project sets out to answer". [1] Choosing a research question is an essential element of both quantitative and qualitative research . Investigation will require data collection and analysis, and the methodology for this will vary widely.
