As one ventures into the expansive world of online baking classes, it's imperative to employ a precise approach to selecting the ideal course. This process echoes the scientific method – forming a hypothesis about what class you need, conducting research through asking pertinent questions, and finally, drawing a conclusion based on the gathered data. Herein, we delve into the kind of questions you should be asking an online baking class instructor to refine this selection process, thereby ensuring the course you opt for is ideally suited to your unique requirements.

The first issue at hand relates to the concept of 'course relevance.' In the study of statistics, we often refer to 'Type I' and 'Type II' errors. Type I errors occur when we falsely reject a true null hypothesis (we find an effect that isn’t there), while Type II errors occur when we fail to reject a false null hypothesis (we miss an effect that is there). Applying this analogy to our course selection, a 'Type I' error would be choosing a course that we think is applicable, but it doesn't meet our needs. A 'Type II' error would be dismissing a program that is, in fact, perfect for our requirements. To mitigate such errors, it is prudent to discuss whether the chosen course aligns with your current skill level and culinary interests, a question that can be posed as, "Does this course match my current baking skills and interests?"

Next, we consider 'course content,' a factor that correlates with the principle of 'opportunity cost' in Economics. The opportunity cost of any action is the value of the highest-valued alternative forgone. In this context, the time and resources dedicated to a particular online baking course could well be invested elsewhere. Thus, it is crucial to inquire about the specifics of the course content, "What techniques, recipes, and skills will this course cover?"

Thirdly, delving into the domain of 'instruction and feedback,' it can be equated with the 'feedback loop' concept in Cybernetics, the study of regulation, control, and feedback. In baking, as in any learning process, feedback is essential for growth and improvement. Therefore, it's advisable to ask, "How will feedback be provided throughout the course?"

Moving onto 'course logistics,' this can be viewed through the lens of Project Management, where factors like timeline, resources, and delivery are crucial for success. Understanding the course logistics would help in proper planning and effective time management. Pose the question, "What is the schedule of the course, and what materials will I need?"

Lastl, the aspect of 'post-course support' can be compared to After-sales service in Marketing, which ensures customer satisfaction even after the purchase. Proficient baking, like any art, requires practice and guidance even after the formal education is over. Therefore, ask, "What kind of support is available after the course ends?"

Indeed, the above exposition represents a comprehensive approach to choosing your online baking course. However, one must remember the principles of Quantum Mechanics, where Heisenberg's Uncertainty Principle posits that one cannot simultaneously know the exact position and momentum of a particle. In our context, it would be impractical to expect total certainty about the course outcome. Some factors will remain unknown until you delve in. As an aspiring baker, armed with the power of the right questions, you can minimize this uncertainty and ensure that the course you choose truly serves your baking journey's objectives.

In the end, the questions you ask your online baking class instructor are not merely inquiries, but strategic tools for decision-making. They reflect your understanding of what you need from the course and what the course offers you. So, ask wisely, and bake well!
