It explains how to enhance the authenticity of research by estimating the sample size and reporting the power of the tests used. Further, it discusses the issue of sample size determination in survey studies as well as in hypothesis testing experiments so that readers can grasp the concept of statistical errors, minimum detectable difference, effect size, one-tail and two-tail tests and the power of the test. The book also highlights the importance of fixing these boundary conditions in enhancing the authenticity of research findings and improving the chances of research papers being accepted by respected journals. ..Further, it explores the significance of sample size by showing the power achieved in selected doctoral studies. Procedure has been discussed to fix power in the hypothesis testing experiment. One should usually have power at least 0.8 in the study because having power less than this will have the issue of practical significance of findings | | 出版日期 | Textbook 2020 | | 关键词 | Sample Size; Power Analysis; Survey Studies; Hypothesis Testing; G* Power; Minimum Detectable Difference; | | 版次 | 1 | | doi | https://doi.org/10.1007/978-981-15-5204-5 | | isbn_softcover | 978-981-15-5206-9 | | isbn_ebook | 978-981-15-5204-5 | | copyright | Springer Nature Singapore Pte Ltd. 2020 |
