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.
In the best experiments, the scientist must be able to measure the values for each variable. Weight or mass is an example of a variable that is very easy to measure. However, imagine trying to do an experiment where one of the variables is love. There is no such thing as a "love-meter." You might have a belief that someone is in love, but you cannot really be sure, and you would probably have friends that do not agree with you. So, love is not measurable in a scientific sense; therefore, it would be a poor variable to use in an experiment.
