The data contains approximately 2500 free-text answers and the full analysis of all phrases in the answers.
 The data consists of the following files:

1. SC_XX Talk_about_Code: free-text answers and descriptive analysis of questions in the following way.
                          The subjects should write down how they would explain a given code section

2. SK_XX Identitify_Concept: free-text answers and descriptive analysis of questions in the following way.
                             The subjects see various static visualizations of content-related concepts. 
                             Then they should identify the represented concept in the visualization.
  
All files have the same structure:

The lines 3-125 each contain the free-text answers of one participant. The corresponding columns contain
 the phrases of the answers. The column named 'adequate' consists of the numerical values 0 and 1,
 where 0 stands for inadequate and 1 for adequate.

Afterward, we list descriptive statistics: empirical probabilities of adequate/inadequate, reasons
 for inadequate, and phrases.
