Could you please post sample questions for both parts of the exams?My response:
One more que: the MCQs on the slides are any representative (of content and level of difficulty) of the questions you might ask in the exam?
Hi V,
Am yet to make the main paper itself. The sample paper will likely have to wait. I hope to release a few sample questions at least 24-36 hrs prior to the exam.
The MCQs will be a mixed bag - some easy, some moderately easy and a select few, tricky. The class slides are more to stimulate discussion, critical thinking etc than to 'settle' an issue this way or that. Hence, no, the MCQs in the exam will leave a lot less room for interpretation and controversy, I hope.

Hi all,
Shall keep updating this post with more mail queries that are sharable with the class at large. So kindly check for updates every once in a while.

Dear Professor,My response:
Would it be possible to please upload the answers to beer dataset practice questions. It will really help us in verifying if we have got the answers right.
Hi S,Sudhir
I haven't made any solutions to the beer dataset myself. However if you wish to share your solutions with the class (anonymously, if so preferred), I'll be most happy to do so on the blog so that other people can compare answers and confirm/disconfirm particular solutions.
Hi all,
ReplyDeleteOne student has emailed me a homework solution for the beer dataset. Except for the price/oz question, the rest looks fine. I shall share it over blackboard. Verify your answers and let me know if something's off.
Re the price/oz question, here's my response:
"Price per SKU is obtained as sales dollars/sales units for the time period of interest. But different SKUs have different sizes – e.g. a 6 pack of 12 oz cans written as 6 P 12 OZ in the PROD description has 6 x 12 = 72 ounces whereas a 12 P 12 OZ has 12x12 = 144 oz. So to better compare prices across SKUs, we normalize price per SKU by SKU size. So we divide the price per SKU of 6 P 12 OZ by 72 and that for 12 P 12 OZ by 144.
Where do the 72 and 144 numbers come from? Well, you’ll have to calculate them for the top 20 SKUs asked for. Often time s, we may have to do lookups, calculations etc also in addition to pivots.
