-====== Keep Score for Responses ======+====== Score Responses ======
  
 In most socio-scientific surveys, we are interested in the participant's opinion. This is not the case if you want to provide feedback on a knowledge test. These have correct and incorrect answers, and a score can be determined. In live analyses (e.g. Thurstone or Likert scales), sometimes a score can also be kept. An analysis of the personality test at the end of the questionnaire can create an incentive. In most socio-scientific surveys, we are interested in the participant's opinion.

 The simplest way of keeping score is for a quiz or a knowledge test. These have a range of selection questions and one of the options is correct for each one.  The simplest way of keeping score is for a quiz or a knowledge test.

-The following PHP code initially defines which questions will be evaluated and what the correct response is. An [[:en:create:array|associative array]] is used accordingly: the variable ID (for selection questions this is the question ID) is used as the key for each entry in the array. Each answer code that will be counted as "correct" is assigned as the value.   +The following PHP code initially defines which questions will be evaluated and what the correct response is. An [[:en:create:array|associative array]] is used accordingly. The arrays are defined here with square brackets (''[]''), the notation with ''array()'' would also be possible.
