 Completely randomized design

A Completely Randomized Design (CRD) is a type of experimental design used in statistics where all experimental units are randomly assigned to different treatment groups without any constraints. This design is typically used in experiments to compare the effects of different treatments or conditions on a dependent variable. ### Key Features of Completely Randomized Design: 1. **Random Assignment**: All subjects or experimental units are assigned to treatments randomly, ensuring that each unit has an equal chance of receiving any treatment.
