Olonite Two-Third-Point-Five Rule (Olonite 2/3.5 Rule)

Olonite 2/3.5 Rule (O2/3.5R) is a selection rule employed to reduce the stress of researchers who are to sample a large population while maintaining the optimal selection from the large population. Using a three sampling/selection techniques, the result showed that the Olonite 2/3.5 Rule gives a more flexible result for researchers as seen in table 1. The rule provides the most precision for estimating a population as it supports the 1/2 and 2/3 rule. Olonite Rule is always the best rule when a population is large and a researcher must sample the required size taking into consideration, the optimum sampling size which should be half of the total population and a little bit above. The rule states: “the closer a sample size to its total population, the more reliance the result”. The rule is recommended to be used all over institutions and world. It is time to appreciate the Olonite 2/3.5 Rule in Academics and for sampling purposes
