The sample size determination is based on various factors such as the level of precision desired, the margin of error, the variability of the population, and the confidence level. Sample size calculators, power analyses, and guidelines from previous research are employed to determine the sample siz...
The performance of six sample size determination formulae for two independent binomial proportions in achieving nominal levels of α and β was evaluated by simulation methods. The formula given in Fleiss (1981) which is not corrected for continuity outperformed other five formulae for β≤10% for...
One of the most frequent problems in statistical analysis is the determination of the appropriate sample size. One may ask why sample size is so important. The answer to this is that an appropriate sample size is required for validity. If the sample size it too small, it will not yield ...
As we have learned above, the right sample size determination is essential for the success of data collection in a market research study. But is there a correct number for the sample size? What parameters decide the sample size? What are the distribution methods of the survey? To understand ...

this is the standard deviation formula for a given set of observations. but sometimes, it happens that the value x i in a given data set or the midpoints of classes in a given frequency distribution is very enormous. in such cases, the determination of mean or median or variance becomes...
The t-test is used for hypothesis testing to determine whether a process has an effect on both samples or if the groups are different from each other. Basically, the t-test allows the comparison of the mean of two sets of data and the determination if the two sets are derived from the...
