Assignment by chance in studies
the process of putting people or things into study groups by chance, not by choice
Μοτίβο χρήσης:
randomization of [participants/patients/samples] to [groups/treatments/conditions]
Συχνό λάθος:
Do not confuse randomization with randomness: randomization is the process; randomness is the quality or result.

|
chance assignment (clearer for non-specialists, but less technical)
Αντώνυμα
nonrandom assignment (assignment not based on chance)
|
systematic allocation (assignment by a fixed rule rather than by chance)

Making order or choice random
mixing or choosing things by chance so they do not always appear the same way
Μοτίβο χρήσης:
randomization of [items/questions/order/results]
Συχνό λάθος:
In everyday speech, shuffle or mix up is often more natural than randomization when talking about songs, cards, or simple order.
Συνώνυμα
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)
Αντώνυμα
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)

Παραδείγματα
- The app uses randomization so the quiz questions do not appear in the same order every time.
- Playlist randomization kept the music from feeling repetitive.
- The game includes randomization of rewards to make each round less predictable.
Παραδείγματα για μαθητές
- The test uses randomization to mix the questions.
- Randomization makes each game a little different.

Adding unpredictability in software
using chance in software so that locations, numbers, or results are harder to predict
Μοτίβο χρήσης:
randomization of [addresses/identifiers/values/output]
Συχνό λάθος:
In computing, randomization often means controlled unpredictability; it does not always mean completely patternless or truly random.
Συνώνυμα
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)
Αντώνυμα
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)

Παραδείγματα
- The browser adds randomization to certain identifiers to make tracking harder.
- Memory randomization makes it more difficult for attackers to predict where code is stored.
- The game uses map randomization so each new world is different.
Παραδείγματα για μαθητές
- The software uses randomization for extra security.
- Randomization helps make the game maps different each time.

Εκφράσεις
address space layout randomization
1/ˈædɹˌɛs spˈeɪs lˈeɪˌaʊt ɹˈændəmɪzˈeɪʃən/
fixed phrase
technical
Randomized memory locations
a security feature that changes where program parts are placed in memory so attackers cannot easily guess their location
Παραδείγματα
- Modern operating systems use address space layout randomization to make memory exploits more difficult.
- The vulnerability was easier to exploit when address space layout randomization was disabled.
- Address space layout randomization is one layer of defense, not a complete security solution.
block randomization
1/blˈɑk ɹˈændəmɪzˈeɪʃən/
fixed phrase
technical
Balanced assignment in blocks
a study method that randomizes people in small sets so the groups stay about the same size
Παραδείγματα
- The researchers used block randomization to keep the treatment and control groups balanced during recruitment.
- Block randomization with varying block sizes helped protect the assignment sequence.
- Each clinic used its own block randomization list.
cluster randomization
1/klˈʌstɚ ɹˈændəmɪzˈeɪʃən/
fixed phrase
technical
Random assignment of groups
randomizing whole groups instead of single people
Παραδείγματα
- The researchers used cluster randomization, assigning entire schools to the new program or the usual curriculum.
- Cluster randomization reduced contamination between students in the same classroom.
- The public health study used village-level cluster randomization.
mendelian randomization
1/mˈɛndˈɛliən ɹˈændəmɪzˈeɪʃən/

Causal study using genetics
a research method that uses genetic differences people are born with to study possible causes of disease
Παραδείγματα
- The paper used Mendelian randomization to examine whether higher BMI increases the risk of asthma.
- Mendelian randomization can strengthen causal evidence when a normal randomized trial is not practical.
- The Mendelian randomization analysis found little support for a causal effect.
randomization ratio
1/ɹˈændəmɪzˈeɪʃən ɹˈeɪʃioʊ/
fixed phrase
technical
Planned assignment proportion
the planned numbers of people put into each study group by chance
Παραδείγματα
- The trial used a 2:1 randomization ratio, so more patients received the experimental treatment.
- A 1:1 randomization ratio gives the same planned number of participants in each group.
- The protocol changed the randomization ratio after the dose-finding stage.
randomization test
1/ɹˈændəmɪzˈeɪʃən tˈɛst/

a statistics method that checks whether a result could happen by chance by repeatedly mixing the data in random ways
Παραδείγματα
- The analyst ran a randomization test by shuffling the treatment labels 10,000 times.
- A randomization test was useful because the sample was small and the usual assumptions were uncertain.
- The randomization test showed that the observed difference was unlikely under the null hypothesis.
simple randomization
1/sˈɪmpəl ɹˈændəmɪzˈeɪʃən/
fixed phrase
technical
Unrestricted random assignment
putting study participants into groups by pure chance, like using a coin toss or random number
Παραδείγματα
- The trial used simple randomization because enrollment was large enough to keep the groups fairly balanced.
- With simple randomization, small studies can end up with unequal numbers in each group.
- The software performed simple randomization for each participant at the time of enrollment.

technical
