How randomisation works
Names are shuffled using the Fisher-Yates algorithm, which guarantees a uniform random permutation — every possible ordering is equally likely. Names are then assigned to groups sequentially from the shuffled list. This produces groups that are as equal in size as possible: if names cannot be distributed perfectly evenly, some groups receive one extra member.
Group size vs group count
You can specify either the number of groups or the target number of people per group. Choosing "4 groups" from 17 people yields groups of 5, 5, 4, 3 (distributing the remainder evenly). Choosing "groups of 4" from 17 people yields 4 groups of 4 and 1 group of 1. For classroom use, "number of groups" mode is usually preferable as it ensures predictable team counts; "people per group" mode is better when a specific collaboration size is required (e.g. pairs or trios).
