Investigation of Psychometric Traits of Metric Scale and Likert Type Scale Applied in Different Conditions
The purpose of this study is to examine the psychometric properties of two different scales (Self-Efficacy Scale about the Method Sections of the Research Papers - SESMSR and The Research Anxiety Scale - TRAS) applied on paper - pencil tests and web. For this purpose, SESMSR and TRAS were applied to 391 undergraduate students in a five - point Likert type scale form and a 10 cm metric form in a paper - pencil environment and then on a web page prepared within the context of the research. The two-factor structure of SESMSR, which is developed to use for the graduate students, appeared exactly the same except for the fact that one item is included in the other factor at the undergraduate level; and it was seen that TRAS, which is known for consisting of one factor, maintained this structure and that the reliability of scales calculated over different data sets is high. For both scales, it was determined that the extracted variance and reliability coefficients obtained with the use of Likert type scale applied as paper - pencil test were lower than the metric scale and the web-based applications. It has been seen that the metric scale which is labeled on both ends can be used instead of the Likert-type scale and the ideal number of category is seven according to investigations.
