The phrase "as a random block" is correct and usable in written English.
It can be used in contexts where you want to refer to something that is arbitrary or not specifically defined, often in programming or data contexts.
Example: "The data was processed as a random block to ensure that the results were unbiased."
Alternatives: "as an arbitrary unit" or "as a random segment".
As operator's selection was based on a block design, sex was treated as a random block effect.
Plot was included as a random block effect in all analyses to account for variability across the landscape.
The possible differences between the three replicate experiments were modeled as a random block effect.
We also considered the possible differences between the two insect lots we used as a random block factor.
In this combined analysis, assay (I and II) was modeled as a random Block effect.
Analysis of antibacterial response was completed with plate as a random block effect to account for variation in bacteria between the plates.
Differences in the abundance and species richness of the different groups of soil organisms, and E1/D of microbial communities, between treatments in the upper 0 6 cm (0 3 and 3 6 cm depth combined to form one sample) were tested using one-way ANOVAs with group as a random blocking factor.
Within each WGP model, we compared homoskedastic vs. heteroskedastic error specifications across the various scenarios using a multifactorial ANOVA on genomic prediction accuracy, with the simulated replicated dataset as a random blocking factor.
To compare average accuracy of genomic evaluation across these four scenarios, we fitted a linear model with the average accuracy of genomic evaluation as response variable and the genotype imputation scenario as independent variable, adding the effect of the random cross-validation dataset in which accuracy of genomic evaluation was estimated as a random blocking factor.
The day on which each jar entered the experiment was inserted into the model as a random categorical blocking factor, 'day', to correct for handling differences.
For future research work, one can try to use the same approach of this paper to extend other experimental designs such as random block design, Latin square design, etc., where the observations are fuzzy numbers rather than being real numbers.
