2.5 Statistical analysis
The main statistical method used in this empirical study was descriptive statistics. The data obtained from the various questionnaires were processed, summarized, and presented appropriately in order to draw meaningful conclusions from the data. With the help of descriptive statistics, it was possible to characterize the sample and to describe and compare the different groups of experts and non-experts. For this purpose, various comparisons of means were carried out, e.g., between experts and non-experts, with the help of the T-test for independent samples. A normal distribution of data was tested and assumed. Additionally, the standard deviation was also considered and included in the comparison. The Data analysis was conducted with the statistical software IBM SPSS (Statistical Package for Social Sciences) and Microsoft Excel program.
