Answer: a study in which subjects are separated into similar groups and then subjects within each group are randomly assigned to treatments

Explanation: In simple words, it refers to an experiment in which the experimenter divides the subject into various sub groups for the ease of research. the groups divided are termed as blocks.

The blocks are prepared in such a way that variability remains low within the blocks however in between blocks it could be relatively high.
