    Pseudoreplication - Wikipedia

    https://en.wikipedia.org/wiki/Pseudoreplication

    Pseudoreplication (sometimes unit of analysis error ) has many definitions. Pseudoreplication was originally defined in 1984 by Stuart H. Hurlbert as the use of inferential statistics to test for treatment effects with data from experiments where either treatments are not replicated (though

    Replication

    Replication increases the precision of an estimate, while randomization addresses the broader applicability of a sample to a population. Replication must be appropriate: replication at the experimental unit level

    Hypothesis testing

    Statistical tests (e.g. t-test and the related ANOVA family of tests) rely on appropriate replication to estimate statistical significance. Tests based on the t and F distributions assume homogeneous, normal, and independent errors. Correlated errors can lead to false

    • Simple pseudoreplication (Figure 5a in Hurlbert 1984) occurs when there is one experimental unit per treatment. Inferential statistics cannot separate variability due to treatment from

    Pseudoreplication The term pseudoreplication was coined by Hurlbert to refer to "the use of inferential statistics to test for treatment effects with data from experiments where either treatments are not replicated (though samples may be) or replicates are not statistically independent." 1 The context of his paper was ecological field experiments, but …

    What is pseudoreplication in statistics?
    Pseudoreplication is the process of artificially inflating the number of samples or replicates. As a result, statistical tests performed on the data are rendered invalid. Pseudoreplication is originally defined as a special case of inadequate specification of random factors where both random and fixed factors are present.

    What is the difference between a pseudoreplicate and a replicate?
    Heffner et al3 distinguish a pseudoreplicate from a true replicate, which they characterize as "the smallest experimental unit to which a treatment is independently applied." Most models for statistical inference require true replication.

    What is a pseudoreplicated peak?
    Pseudoreplicated peaks are peaks from the relaxed set that overlap at least 50% with peaks from both pseudoreplicates. Peaks derived from IDR analysis of biological replicates. IDR, or Irreproducible Discovery Rate, measures the reproducibility of the assay in question.

    Pseudoreplication: choose your data wisely¶. Many studies strive to collect more data through replication: by repeating their measurements with additional patients or samples, they can be more certain of their numbers and discover subtle relationships that aren’t obvious at first glance.

Now we come to the third part of our trifecta; in the last two posts I have gone over p-values and how they determine significance in null hypothesis testing, and we talked about degrees of freedom and their effect on the p-value.
