Assignment by chance in studies
the process of putting people or things into study groups by chance, not by choice
用法パターン：
randomization of [participants/patients/samples] to [groups/treatments/conditions]
よくある間違い：
Do not confuse randomization with randomness: randomization is the process; randomness is the quality or result.

Making order or choice random
mixing or choosing things by chance so they do not always appear the same way
用法パターン：
randomization of [items/questions/order/results]
よくある間違い：
In everyday speech, shuffle or mix up is often more natural than randomization when talking about songs, cards, or simple order.
類義語
shuffling (common and informal when the main idea is mixing the order)
|
random ordering (emphasizes the order of items)
|
random selection (emphasizes choosing items rather than arranging them)
対義語
fixed ordering (items appear in a set order)
|
deliberate selection (items are chosen intentionally rather than by chance)
|
deterministic ordering (the order is fully determined by a rule or input)

Adding unpredictability in software
using chance in software so that locations, numbers, or results are harder to predict
用法パターン：
randomization of [addresses/identifiers/values/output]
よくある間違い：
In computing, randomization often means controlled unpredictability; it does not always mean completely patternless or truly random.
類義語
random variation (broader and less technical)
|
randomized layout (specific to arranging software or memory locations)
|
unpredictable generation (emphasizes generating values that cannot easily be guessed)
対義語
fixed layout (locations or arrangements do not change)
|
deterministic behavior (the same input always produces the same predictable result)
|
predictable output (results can be anticipated rather than randomized)
