nuisance factors

(noun)

Variables that may affect the measured results, but are not of primary interest.

Examples of nuisance factors in the following topics:

  • Randomized Block Design

    • However, there are also several other nuisance factors.
    • Nuisance factors are those that may affect the measured result, but are not of primary interest.
    • All experiments have nuisance factors.
    • When we can control nuisance factors, an important technique known as blocking can be used to reduce or eliminate the contribution to experimental error contributed by nuisance factors.
    • The basic concept is to create homogeneous blocks in which the nuisance factors are held constant and the factor of interest is allowed to vary.

  • Randomized Design: Single-Factor

    • Completely randomized designs study the effects of one primary factor without the need to take other nuisance variables into account.
    • In the design of experiments, completely randomized designs are for studying the effects of one primary factor without the need to take into account other nuisance variables.
    • All completely randomized designs with one primary factor are defined by three numbers: $k$ (the number of factors, which is always 1 for these designs), $L$ (the number of levels), and $n$ (the number of replications).
    • $L$: 4 levels of that single factor (called 1, 2, 3, and 4)
    • Discover how randomized experimental design allows researchers to study the effects of a single factor without taking into account other nuisance variables.

  • Biological Effects of Radiation

    • Deterministic effects are not necessarily more or less serious than stochastic effects; either can ultimately lead to damage ranging from a temporary nuisance to death.
    • Stochastic effects can only be measured through large epidemiological studies in which enough data have been collected to remove confounding factors such as smoking habits and other lifestyle factors.

  • Advertising and Brand Management in Monopolistic Competition

    • Some believe that advertising and branding induces customers to spend more on products because of the name associated with them rather than because of rational factors.
    • Finally, advertising can have negative societal effects such as the perpetuation of negative stereotypes or the nuisance of "spam. "

  • Experimental Design

    • Factorial experiments: Use of factorial experiments instead of the one-factor-at-a-time method.
    • These are efficient at evaluating the effects and possible interactions of several factors (independent variables).
    • Analysis of experiment design is built on the foundation of the analysis of variance, a collection of models that partition the observed variance into components, according to what factors the experiment must estimate or test.
    • To control for nuisance variables, researchers institute control checks as additional measures.

  • Corrosion

    • Corrosion is a common nuisance with real impact.

  • When Does the Z-Test Apply?

    • Nuisance parameters should be known, or estimated with high accuracy (an example of a nuisance parameter would be the standard deviation in a one-sample location test).
    • In practice, due to Slutsky's theorem, "plugging in" consistent estimates of nuisance parameters can be justified.

  • Profit and Stakeholders

    • In the case of a professional landlord undertaking the refurbishment of some rented housing that is occupied while the work is being carried out, key stakeholders would be the residents, neighbors (for whom the work is a nuisance), and the tenancy management team and housing maintenance team employed by the landlord.

  • The Role of Species within Communities

    • Local and national politicians have weighed in on how to solve the problem, but no one knows whether the Asian carp will ultimately be considered a nuisance, like other invasive species, such as the water hyacinth and zebra mussel, or whether it will be the destroyer of the largest freshwater fishery of the world.

  • Factors

    • This is a complete list of the factors of 24.
    • Therefore, 2 and 3 are prime factors of 6.
    • However, 6 is not a prime factor.
    • To factor larger numbers, it can be helpful to draw a factor tree.
    • This factor tree shows the factorization of 864.
