Assignment by chance in studies

the process of putting people or things into study groups by chance, not by choice

Schema d'uso: randomization of [participants/patients/samples] to [groups/treatments/conditions]
Errore comune:
Do not confuse randomization with randomness: randomization is the process; randomness is the quality or result.
Sinonimi
random assignment (the most direct synonym in experiments and trials) | random allocation (common in medical and statistical research) | chance assignment (clearer for non-specialists, but less technical)
Contrari
nonrandom assignment (assignment not based on chance) | systematic allocation (assignment by a fixed rule rather than by chance)
Collocazioni
patient randomization |treatment randomization |randomization process |randomization procedure |randomization scheme |randomization method |randomization list |randomization code |proper randomization |concealed randomization
Temi
statistics |research |medicine |science
Esempi
  • Randomization assigned half the patients to the new drug and half to standard treatment.
  • Good randomization helps reduce bias between the treatment and control groups.
  • The study was criticized because it did not clearly describe its randomization procedure.
Esempi per chi studia
  • Randomization put the patients into two groups by chance.
  • The trial used randomization to make the results fairer.

Making order or choice random

mixing or choosing things by chance so they do not always appear the same way

Schema d'uso: randomization of [items/questions/order/results]
Errore comune:
In everyday speech, shuffle or mix up is often more natural than randomization when talking about songs, cards, or simple order.
Sinonimi
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)
Contrari
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)
Collocazioni
order randomization |question randomization |item randomization |playlist randomization |data randomization |automatic randomization |randomization algorithm |randomization setting |complete randomization |controlled randomization
Temi
technology |education |games |data
Esempi
  • 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.
Esempi per chi studia
  • 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

Schema d'uso: randomization of [addresses/identifiers/values/output]
Errore comune:
In computing, randomization often means controlled unpredictability; it does not always mean completely patternless or truly random.
Sinonimi
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)
Contrari
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)
Collocazioni
memory randomization |address randomization |layout randomization |identifier randomization |port randomization |randomization technique |randomization layer |runtime randomization |security randomization |seeded randomization
Temi
computing |cybersecurity |software |privacy |games
Esempi
  • 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.
Esempi per chi studia
  • The software uses randomization for extra security.
  • Randomization helps make the game maps different each time.

Espressioni

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

Esempi
  • 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

Esempi
  • 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

Esempi
  • 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/
fixed phrase technical

Causal study using genetics

a research method that uses genetic differences people are born with to study possible causes of disease

Esempi
  • 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

Esempi
  • 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/
fixed phrase technical

Significance test by reshuffling

a statistics method that checks whether a result could happen by chance by repeatedly mixing the data in random ways

Esempi
  • 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

Esempi
  • 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.

stratified randomization

1
/stɹˈætəfˌaɪd ɹˈændəmɪzˈeɪʃən/
fixed phrase technical

Randomization within subgroups

randomizing people separately inside groups with the same important feature, such as age or clinic

Esempi
  • The trial used stratified randomization by age and disease severity.
  • Stratified randomization helped ensure that each treatment group had similar numbers of high-risk patients.
  • The protocol specified stratified randomization within each study site.
