Random assignment or random placement is an experimental technique for assigning human participants or animal subjects to different groups in an experiment (e.g., a treatment group versus a control group) using randomization, such as by a chance procedure (e.g., flipping a coin) or a random number generator.

The Every Student Succeeds Act (ESSA) is a US law passed in December 2015 that governs the United States K–12 public education policy. [1] The law replaced its predecessor, the No Child Left Behind Act (NCLB), and modified but did not eliminate provisions relating to the periodic standardized tests given to students.
Funding was first authorized under the CCDBG Act of 1990, which was enacted under the Omnibus Budget Reconciliation Act of 1990. [4]Since CCDBG’s inception, much has been learned about the role of early learning and development on the success of a child, and CCDBG has become an important tool not just for helping families work, but also for helping them ensure their children get a strong ...
The Elementary and Secondary Education Act (ESEA) was passed by the 89th United States Congress and signed into law by President Lyndon B. Johnson on April 11, 1965. Part of Johnson's "War on Poverty", the act has been one of the most far-reaching laws affecting education passed by the United States Congress, and was reauthorized by the No Child Left Behind Act of 2001.
It provides accommodations, modifications, related services, and specialized academic instruction to ensure that every eligible child receives a "Free Appropriate Public Education" (FAPE) in the "Least Restrictive Environment" (LRE). The IEP is intended to help children reach educational goals more easily than they otherwise would.
You may choose to randomly assign experimental units to treatment conditions within each block which may help ensure that any unaccounted for variability is spread evenly across treatment groups. However, depending on how you assign treatments to blocks, you may obtain a different number of confounded effects. [ 4 ]
Randomization is a statistical process in which a random mechanism is employed to select a sample from a population or assign subjects to different groups. [1] [2] [3] The process is crucial in ensuring the random allocation of experimental units or treatment protocols, thereby minimizing selection bias and enhancing the statistical validity. [4]
For example, random assignment in randomized controlled trials helps scientists to test hypotheses, and random numbers or pseudorandom numbers help video games such as video poker. These uses have different levels of requirements, which leads to the use of different methods.
