There have 3 independent variables which are knowledge, perception, and awareness. My dependent variable is buying decisions. The question in my questionnaire only has demographic and IV questions. But the IV questions represent their buying decision. So I still need to create dependent variable question? My hypothesis is looking for the different status (worker and student) of their buying decision.
You could create an intention to purchase or purchase construct - refer to some my articles on ResearchGate as examples.
Rodney Duffett my questionnaire is for those who have been to the mall to buy products. Each of the questions represents their buying decision. Is it still need dependent variable question?
Is there a question in your questionnaire that asks if they have purchased a product? Secondly, did the respondents have to buy something in order to participate in the survey? If not, then you could use this question as a dependent variable.
For a statistical test involving an IV and DV, each needs to be measured independently of the other. You cannot have one variable that measures both.
Thank you David L Morgan as always for your vast experience and valuable input!
Rodney Duffett Yes. My questionnaire for those who have purchased a product.
David L Morgan Can I sum the data of knowledge, perception, and awareness as their buying decision (DV) data? Since the question is for those who had been bought the product in the mall.
I would keep the three as separate scales, but you can investigate whether they do form a single scale.
I am still having problems determining what your independent variable is. Do you have a measure that consists of did or diid not purchase, or do you only have purchasers?
David L Morgan My independent variable is the level of knowledge, perception, and awareness. Yes, only have purchasers.
Dear Aziz Ikmal , as your questions do not clear the purpose of your study, try to clearly understand the basic objectives of your study first. Rodney Duffett is very right that for the buyers of certain products as your target population you should have included Repurchase Intention as well to have your Dependent Variable measured. Without separately measured IVs and DV from the same respondents you cannot move forward for the quantitative analysis part of your study. Try to take advice from your advisors or seniors to better understand the research process and the role of research objectives. Tq.
Yes! You need to create a question for the dependent variable in your questionnaire. Your questionnaire must capture both the dependent variable and the independent variables.
Kindly consider the valuable inputs earlier made in response to your question.
