1. A method of integrated batching and random sampling of documents for enhanced functionality within document review processes, comprising: receiving a batching request, the batching request including: a population size that corresponds to a total amount of documents available for sampling; and an acceptable margin of error; computing a random sample size from the batching request; randomly selecting a subset of documents from the total amount of documents available for sampling, the subset of documents corresponding to the random sample size; grouping the subset of documents into one or more batches; and assigning the one or more batches to one or more review nodes.
