In research, determination of sample size to be used for research has generated a lot of controversy. Sample size and power estimation is an important concern for researchers undertaking research projects but most often than not they have been misunderstood or ignored completely.

I came across these online sample size calculators today. They can ease the stress involved in the research process.

2. POWER AND SAMPLE SIZE (PASS) SOFTWARE:
As the name implies, the power and sample size calculator/software is a unique software that helps to calculate the power and sample size of a research/survey.
Most times, researchers make the mistake of rejecting a true null hypothesis (Ho). The power of the test needs to be ascertained as a guide in knowing if the research is making the right decision i.e. rejecting a null hypothesis that is actually false and accepting its alternative or vice-versa.
This unique software helps in determining if the research is judge “powerful” by placing it on a probability scale of 0 to 1.
