Standardized Questionnaires

Here is a (German) overview of several HCI methods and questionnaires. There are many standardized questionnaires for various items to measure. Look at related works to find out which ones are used most frequently in your field of work.  Some examples are:

• the System-Usability Scale (SUS) to measure the usability of a system
• the NASA Task Load Index (TLX) to measure the perceived workload of a task
  
• the User Experience Questionnaire (UEQ) to measure the subjective impression of a user regarding the system
• the IPQ to measure presence in VR

To analyse qualitative feedback, HCI most often uses a Thematic Analysis by Braun and Clarke (how'to and actual paper) or a qualitative content analysis, e.g. by Mayring.
