How is Randomization Implemented in Histological Studies?
Randomization can be implemented in several ways in histological studies:
Simple Randomization: Each sample is assigned to a group purely by chance, often using random number generators or lottery methods. Stratified Randomization: Samples are divided into strata or subgroups based on specific characteristics (e.g., age, sex, disease stage), and randomization occurs within each stratum to ensure balanced representation. Block Randomization: Samples are divided into blocks of a predetermined size, and within each block, randomization is performed. This approach helps in maintaining balance across groups.
