商品描述
This book addresses sample size and power in the context of research, offering valuable insights for graduate and doctoral students as well as researchers in any discipline where data is generated to investigate research questions. 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. If the power in any study is less than 0.5 then it would be better to test the hypothesis by tossing a coin instead of organizing the experiment. It also discusses determining sample size and power using the freeware G*Power software, based on twenty-one examples using different analyses, like t-test, parametric and non-parametric correlations, multivariate regression, logistic regression, independent and repeated measures ANOVA, mixed design, MANOVA and chi-square.
商品描述(中文翻譯)
本書探討了研究中的樣本大小和檢定力，為研究生、博士生以及任何產生數據以調查研究問題的研究人員提供了寶貴的見解。它解釋了如何通過估算樣本大小和報告所使用檢定的檢定力來增強研究的真實性。此外，本書還討論了在調查研究和假設檢定實驗中確定樣本大小的問題，以便讀者能夠理解統計錯誤、最小可檢測差異、效應大小、單尾和雙尾檢定以及檢定力的概念。本書還強調了在增強研究結果的真實性和提高研究論文被受尊敬的期刊接受機會方面，修正這些邊界條件的重要性。
此外，本書通過展示在選定的博士研究中所達到的檢定力，探討了樣本大小的重要性。書中討論了在假設檢定實驗中修正檢定力的程序。通常，研究中的檢定力應至少為0.8，因為檢定力低於此將會影響研究結果的實際意義。如果任何研究的檢定力低於0.5，那麼進行實驗不如擲硬幣來檢驗假設。本書還討論了如何使用免費軟體G*Power來確定樣本大小和檢定力，並基於二十一個使用不同分析的範例，如t檢定、參數和非參數相關、多變量回歸、邏輯回歸、獨立和重複測量ANOVA、混合設計、MANOVA和卡方檢定。
