I have a question, suppose I have a variable “Gender Diversity”. In my survey questionnaire I have three questions about it. So, when I want to check the relationship between “gender diversity” and “performance of the firm”, what shall I do to make a scale on SPSS? Like three questions make one variable but when checking this variable, which question shall I consider out of three or shall I combine all three questions and divide it by the number of questions to make representative variable?
Note: I am using LIKERT Scale for this survey.
