Some radioactive iodide salts of sodium, including [ 125I ]NaI and [ 131I ]NaI, have radiopharmaceutical uses, such as in the treatment of thyroid cancer and hyperthyroidism or as radiolabeling tracers in imaging (see).
Genetic drift is defined as the changing of the number of available alleles in a population by chance events. Also called allelic drift, this phenomenon is usually due to a very small gene pool or population size.
Statistics: Scientific method Â· Research methods Â· Experimental design Â· Undergraduate statistics courses Â· Statistical tests Â· Game theory Â· Decision theory. Randomization is the process of making something random; this can mean: Generating a random permutation of a sequence (such as when shuffling cards). Selecting a random sample of a population (important in statistical sampling). Generating random numbers: see Random number generation. Applications Edit. Randomization is used extensively in the field of gambling. Imperfect randomization may allow a skilled gambler to have an advantage, so much research has been devoted to effective randomization. A classic example of randomization is shuffling playing cards.
