Kid3 tag editor explicit7/31/2023 Slow - database intensive -it can slow down long surveys.Ĥ. Only supports simple comparisons and does not "AND" and "OR" conditions well.ģ. GUI well documented and understood by support teamġ. Nice GUI for creating simple conditions.Ģ. Here is a list of the pros and cons of each style:ġ. How should I choose between Conditions and Relevance? Delete the newly created condition from the Conditions editor and then edit the question by adding the condition-based expressions from your text editor file alongside the rest of expressions you wish to use. Once done, check what is the newly created equation and copy it in a text editor. As mentioned above, a condition replaces the relevance equation field. Yet, there is a way to use both expressions and conditions within a question. Moreover, the Relevance equation field cannot any longer be manually edited. You cannot have both conditions and expressions set up in the same question! Once a condition is set up, it replaces whatever expression is written in the relevance equation field. You can use the Conditions editor for some questions and Relevance equations for others. That is why the EM is used - it expands the realm of customization possibilities.Ĭan I mix Conditions and Relevance equations? However, the Conditions editor is limited. However, this heavily depends on the complexity of the survey you want to create.įor example, the Conditions editor covers some basic expressions that can be applied to the questions of your survey. So, if you do statistical analysis, you need to create only unique question codes. This is what becomes the variable name if you export data to SPSS or R.Valid question codes should NOT start with a number, so when using the question code to number your questions, simply use "q1", or "q1a" or "g1q2".This can be a descriptive name indicating the purpose of the question, making it easier to read complex logic.Question Code: This is the preferred variable name for EM:.It is like a Boilerplate question, but its contents are saved to the database even if you set "Always Hide this Question".Equation Question Type: A new question type that saves calculations or reports to the database:.These variable names are specific to the underlying S/Q/G/A database codes, so they often need to be changed.SGQA variable names look like 123X5X382X971, and may have subquestion suffixes.Stands for Survey-Group-Question-Answer.SGQA (how variables were named in the past):. Internally, all array_filter and array_filter_exclude commands become subquestion-level relevance.If there is a relevance equation, then the question is only shown if the relevance evaluates to true.Relevance Equation: A new question attribute controlling question visibility:.You also have easier access to questions, answers, and their properties.You have access to all 'replacement fields', participant data, and response data.It is the process of conditionally modifying text: The expression content is evaluated by EM, so it can contain mathematical formulas, functions, and complex string and date processing.As long as there is no white space immediately after the opening brace or before the closing curly brace.Expression: Anything surrounded by curly braces:.It also speeds up processing considerably since it eliminates most run-time database reads. It replaces how LimeSurvey manages Replacements, Conditions, and Assessments on the back-end. LimeSurvey uses the new ExpressionScript (EM) module which lets LimeSurvey support more complex branching, assessments, validation, and tailoring. 13.1 Types and Meanings of Syntax Highlighting.12 How does ExpressionScript support conditional micro-tailoring?.11 ExpressionScript knows which variables are local.10.2 Create new expression functions with plugin (New in 4.0.0 ).9 The reserved "this", "self", and "that" variables.4.2 Caution about using Assignment Operator (=).
