Statisticians attempt to collect samples that are representative of the population in question. With smaller sample size in a study, it may not be able to detect the precise difference between study groups, making the study unethical. But as the sample size increases, the same RCT may be able to demonstrate a significant effect of the treatment, even if this effect is small. In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. Having no access to the experimental methods of science, Greek philosophers used reasoning, intuition, and speculation to build their theories. Research Sampling and Sample Size Determination The initial sample size is projected to be 572 subjects to achieve 400 subjects with a "recovered" status (per the primary objective). This weir has a rectangular opening where the sides are straight up and down. An alpha value of p = .05 is commonly used. Probability Sampling This means that the probability that the results found are due to chance alone is .05, or 5%, and 95% of the time a difference found between the control group and the experimental group will be statistically significant and due to the manipulation or treatment.
