Computation is a function in the 1KA tool that enables you to make various calculations.

Computed values are set primarily in various quizzes and tests, where we want to compute the outcome, depending on the value of individual responses to the questionnaire.

  • The following operators can be used when using calculations:

+ ,- ,* , /.

  • A number of decimals can also be changed.
  • In some cases (eg. Belbin's test), where a respondent doesn't need to answer all the questions or when making additions or subtractions, it is possible to ´treat missing values as 0´ by using the function 'Missing as value 0'. In this case, calculations are made, but missing values are treated as value 0. We must urge caution that results are not correct when using this function for multiplications and divisions.
  • Results of a calculation can also be displayed within a survey. A page break must be inserted behind a calculation to achieve this. Then the function 'data piping' can be used in any question type.

The calculation is conducted only if all questions included in it have valid responses. If not, value -88 is displayed as a result. This means that an error was made during the calculation. We recommend that all questions included in the calculation have hard reminders.

The result of the calculation is shown in the data, analyses (e.g. averages, frequencies), graphs.
