The article "Likert Scale: Explored and Explained" by Ankur Joshi, Saket Kale, Satish Chandel, and D. K. Pal, published in the Journal of Applied Science and Technology, explores the Likert scale as a fundamental psychometric tool in educational and social sciences research. The authors review the literature and provide a coherent scientific perspective on the Likert scale, addressing issues such as validity, reliability, and analysis. They discuss the necessity of psychometric tools like the Likert scale for quantifying qualitative attributes such as attitudes, perceptions, and opinions. The article delves into the constructional diversities of Likert scales, including symmetric versus asymmetric scales and 7/10-point scales, and their implications for analysis. It also debates the superiority of 7-point versus 5-point scales in terms of reliability and validity, considering factors such as the clustering of attitudes and the practicality of response options. The authors conclude that the choice between ordinal and interval scales for Likert data depends on the research objectives and the construct of the research instrument, emphasizing the importance of aligning the scale type with the research design to ensure accurate and valid results.The article "Likert Scale: Explored and Explained" by Ankur Joshi, Saket Kale, Satish Chandel, and D.
