  2. Probabilistic method - Wikipedia

    en.wikipedia.org/wiki/Probabilistic_method

    Alternatively, the probabilistic method can also be used to guarantee the existence of a desired element in a sample space with a value that is greater than or equal to the calculated expected value, since the non-existence of such element would imply every element in the sample space is less than the expected value, a contradiction.

  3. Stochastic - Wikipedia

    en.wikipedia.org/wiki/Stochastic

    The Monte Carlo method is a stochastic method popularized by physics researchers Stanisław Ulam, Enrico Fermi, John von Neumann, and Nicholas Metropolis. [33] The use of randomness and the repetitive nature of the process are analogous to the activities conducted at a casino. Methods of simulation and statistical sampling generally did the ...

    Also confidence coefficient. A number indicating the probability that the confidence interval (range) captures the true population mean. For example, a confidence interval with a 95% confidence level has a 95% chance of capturing the population mean. Technically, this means that, if the experiment were repeated many times, 95% of the CIs computed at this level would contain the true population ...

    en.wikipedia.org/wiki/Convenience_sampling

    Through this method, researchers can easily finish collecting their data in a matter of hours, free from worrying about whether it is an accurate representation of the population. [5] This allows for a great ease of research, letting researchers focus on analyzing the data rather than interviewing and carefully selecting participants.

  6. List of probabilistic proofs of non-probabilistic theorems

    en.wikipedia.org/wiki/List_of_probabilistic...

    Probability theory routinely uses results from other fields of mathematics (mostly, analysis). The opposite cases, collected below, are relatively rare; however, probability theory is used systematically in combinatorics via the probabilistic method. They are particularly used for non-constructive proofs.

  7. Snowball sampling - Wikipedia

    en.wikipedia.org/wiki/Snowball_sampling

    Snowball sampling is a recruitment method that employs research into participants' social networks to access specific populations. According to research mentioned in the paper written by Kath Browne, [20] using social networks to research is accessible. In this research, Kath Browne used social networks to research non-heterosexual women.

  8. Sampling (statistics) - Wikipedia

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

    In social science research, snowball sampling is a similar technique, where existing study subjects are used to recruit more subjects into the sample. Some variants of snowball sampling, such as respondent driven sampling, allow calculation of selection probabilities and are probability sampling methods under certain conditions.
