Single nucleotide polymorphisms, frequently called SNPs (pronounced âsnipsâ), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide.
Below is a definition of random assignment: Random Assignment Definition Random assignment is a procedure in conducting experiments in which each participant has the same probability of being assigned to a particular condition of the experiment.
We achieve probabilistic equivalence through the mechanism of random assignment to groups. When we randomly assign to groups, we can calculate the chance that the two groups will differ just because of the random assignment (i.e., by chance alone).
