2. (Statistics) statistics a. having a value which cannot be determined but only described probabilistically: a random variable. b. chosen without regard to any characteristics of the individual members of the population so that each has an equal chance of being selected: random sampling. 3...

In an experiment, random assignment means placing your participants into control and experimental groups at random.

Note that all values of pr(x) are between 0 and 1 and sum to 1 so this is a valid assignment of probabilities to the values of the random variable. The probability distribution pr(x) of the random variable X= the number of heads observed in three tosses of a fair coin describes how...
In this case, assignment of the correlation function B(r,t;r′,t′) = 〈f(r,t)f(r′,t′)〉. describes all statistical characteristics of the field. For statistically homogeneous and stationary random field f(r, t), we have B(r,t;r′,t′) = B(r−r′,t−t′). ...
4 and 3, the null-model was obtained by considering 100 independent realisations of the corresponding class assignment. Spurious effects for c ≃ 1 Coverage time distributions for a city will in general depend on the abundance of the classes and on how they are distributed in space. In...
Under this model, the maximum likelihood estimator is equivalent to solving the intractable quadratic assignment problem. This work develops an -time algorithm which perfectly recovers the true vertex correspondence with high probability, provided that the average degree is at least and the two graphs ...
Evaluation using random assignment experiments: demonstrating the effectiveness of earnings supplements (If the Scream franchise is any indication, the general public is more sophisticated about the genre than lofty filmmakers who view it from atop an ivory abattoir.) Instead, the camera's disengagement...
