Research Reliability and Validity

Research Reliability and Validity

English / 英文

Reliability and validity are crucial concepts in research methodology that ensure the quality and trustworthiness of research findings. Reliability refers to the consistency and stability of the measurements across different instances. Validity addresses the extent to which the instrument accurately measures what it is intended to measure. Various types of reliability and validity exist, each serving a specific purpose and context.

Traditional Chinese / 繁體中文

研究信度和效度是研究方法學中確保研究結果質量和可信度的關鍵概念。信度指的是在不同情況下測量的一致性和穩定性。效度則涉及到工具是否準確地測量其旨在測量的內容。各種類型的信度和效度都有其特定的目的和語境。

Academic Relevance / 學術重要性

In the academic field, the rigor of research is often evaluated based on the reliability and validity of its methods and findings. Employing reliable and valid measures not only enhances the integrity of the research but also its generalizability and applicability in broader contexts (Cronbach & Meehl, 1955; Shadish, Cook, & Campbell, 2002).

在學術領域中，研究的嚴謹性通常是基於其方法和結果的信度和效度來評估的。使用可靠和有效的測量方法不僅增強了研究的完整性，而且提高了其在更廣泛語境中的普適性和適用性（Cronbach & Meehl, 1955; Shadish, Cook, & Campbell, 2002）。
