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 number of 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, a number of the randomly selected subset of documents corresponding to the random sample size, a set of excluded documents being documents in the total amount of documents available for sampling that are not included in the randomly selected subset of documents; determining a range of relevant documents within the set of excluded documents by determining a population of relevant documents within the set of excluded documents, the determination performed by: receiving a query regarding the total amount of documents, applying a hypothesis test to the randomly selected subset of documents to calculate a first response to the query for the randomly selected subset of documents, and utilizing the first response to calculate a second response to the query for the population of excluded but relevant documents within the total amount of documents; randomly grouping the randomly selected subset of documents into a plurality of batches for assignment to a plurality of review nodes, at least one review node being a machine review node and at least one node being a human review node; assigning each of the randomly grouped batches to a review node of the plurality of review nodes for review of the respective batch; determining a range of excluded but relevant documents for both a batch of machine reviewed documents and a batch of human reviewed documents; comparing the ranges together to determine a difference between machine reviewed documents and human reviewed documents; and utilizing machine document review if the difference is less than a threshold amount.
