Question

vThe purpose of marketing research is to improve marketing and business decision-making. We are going to return to CC’s mobile application. Which gender is more likely to use the app? We administer a questionnaire to students that measures potential usage on a scale of 1–7 on the various features they will use (1 = never use and 7 = always use). “We gather some sample data and observe that the two groups have different average scores. But does this represent a real difference between the two populations, or just a difference in our sample, which might not be representative of the true population (e.g., unlucky random sample, or convenience sampling, etc.)?” (Creech, “T-Test”). Explain your answer.

Answer 1

The difference between the two average scores will represent the difference between samples only, it does not represent a real difference between the two populations because the questionnaire was administered to only those students who measure potential uses of various features, they will use hence it cannot be generalized to all students.

Good luck with your studies!!!
