The scaling method with pairwise comparisons was developed by Thurstone (1927). In this scaling method, participants are asked to choose one of the pairs of stimuli presented to them over the other. Non-chose judgments are not allowed (Turgut & Baykul, 1992). After the presented stimuli are compared in pairs by the observers, statistical processes for calculating the scale values for each stimulus are started. The steps followed in this context, I. creating the frequency matrix, II. calculating the ratio matrix, III. obtaining the unit normal deviations matrix, IV. finding the average of each column in the unit normal deviation matrix, and V. applying a shift to the found averages that will shift the starting point of the scale values to zero (Erkuş, 2019; Tekindal, 2015). With the completion of these steps, the data collected by pairwise comparisons are brought to the level of an evenly spaced scale (Güler et al., 2018). Also, this procedure was re-executed separately for females and males. All calculations regarding the paired comparison scaling process in this study were using Google Sheets.
