There are many statistical methods that could try to prevent this from influencing the reliability of the study. However, one common logical approach in statistics is to initiate random trials in response to selecting or acquiring of data. The RCT, as a research design and as the name implies, would try to randomise in choosing actual samples in order to give equal chance for each member of the population to be randomly chosen. This is such a very effective method because one could probably deter bias along the way resulting to generation of a more reliable information. In randomisation effort, the implication for this treatment would pave the way for considering the entire generated samples to represent the entire population.For example, by investigating the probable impact of certain chemicals or drugs on the human health, a common study is to employ animals like rats and monkeys. These animals may be randomly subdivided into different groups, in which some of them receive the treatments at varying dosage or by considering other relevant factors and related concerns. On the other hand, the control group will receive no treatment at all, as a reference point in order to find out the necessary information needed from the actual investigation process. Randomisation of selecting samples is in reality a most feasible approach because in the actual setting it would be impossible to use the entire population. Aside from it is going to be costly, not everyone in the first place would be willing to participate in the actual studies.In other words, the RCT in general is trying to create an inference of a particular intervention by randomly employing samples from the entire population that should therefore be randomly identified as the treatment or intervention groups and control groups (Bonita et al., 2006, p. Below is the actual diagram or framework showcasing the general flow involved in the RCT research design (Evidenced-Based Dentistry, 2013).The good thing about RCT is the comparability of the control and treatment groups at the start of the investigation provided that the execution of initial selection or randomisation process is appropriate (Bonita et al., 2006, p.The comparability of generated samples out from randomised allocation from the study sample is therefore dependent on the execution of initial selection. Therefore, if the initial selection process is not properly
