Answer:
Dependent variable
Step-by-step explanation:
The dependent variable can be defined as the variable been investigated in the course of an experiment. It usually portrays the outcome of an experiment, if it isn't the outcome itself.
From the research done in the question, flavor perception (of customers) is the dependent variable as it is the variable being investigated.
NOTE: An independent variable is the variable that is intentionally or unintentionally altered by the researcher him/herself but IS NOT affected by any other variable. The independent variable here are the participants.
