There are many statistical methods that could try to prevent this from influencing the reliability of the study. Hwever, oe common logical approach in statistics is to initiate random trials in response to selecting or acquiring of data. Te RCT, a a research design and as the name implies, wuld try to randomise in choosing actual samples in order to give equal chance for each member of the population to be randomly chosen. Tis is such a very effective method because one could probably deter bias along the way to generation of a more reliable information.

I randomisation effort, te implication for this treatment would pave the way for considering the entire generated samples to represent the entire population. Fr example, b investigating the probable impact of certain chemicals or drugs on the human health, acommon study is to employ animals like rats and monkeys. Tese animals may be randomly subdivided into different groups, i which some of them receive the treatments at varying dosage or by considering other relevant factors and related concerns. O the other hand, control group will receive no treatment at all, a a reference point in order to find out the necessary information needed from the actual investigation process.

Rndomisation of selecting samples is in reality a most feasible approach because in the actual setting it would be impossible to use the entire population. Aide from it is going to be costly, nt everyone in the first place would be willing to participate in the actual studies. I other words, te RCT in general is trying to create an inference of a 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). Te 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, pThe comparability of generated out from randomised allocation from the study sample is therefore dependent on the execution of initial selection.

Terefore, i the initial selection process is not properly...
