1.2 Forming RQs
A cafe owner doesn’t believe that his customers can taste the difference between diet and regular softdrinks. As a result, the cafe owner decides to conduct a study of his customers for a SCI110 project.
Two RQs that the cafe owner is considering are given below. Which do you prefer, and why?
- Among my Wednesday customers, is the average customer-taste rating the same for diet and regular lemonade soft drinks?
- Among my Wednesday customers, is the percentage of customers who prefer diet lemonade soft drink the same as the percentage of customers who prefer regular lemonade soft drink?
Make some notes about how the cafe owner could answer the question using an observational study. What would be the best type of observational study: retrospective, prospective, or cross sectional?
Make some notes about how the cafe owner could answer the question using an experimental study. What would be the best type of experimental study: true or quasi?
List some advantages and disadvantages of the experimental and observational studies.
List some similarities and differences between the two studies.
Which do you think would be the better study? Why?
