Update: Quant sessions Homework related
Got this email from SS:
More generally:
The quant side home-works emphasize practice. More than that, data preparation, some re-coding here and there, data cleaning to get rid of incomplete or nonsensical responses from the analysis frame and so on. These are common issues that will crop up in the analysis phase of almost all Quantitative MKTR. It important you know how to address and get around these. However, I don't need to know the details of how you got around these obstacles - there are various, equivalent ways of doing so. I just want the final answers - whether something was significant or not, the hypotheses as formulated, null rejected or not, what the p-value is etc. Followed by what this means for MKTR recommendations and the decision problem. In a few lines. That's all.
Another way to think of it is that the homework is an exec summary of the work you've done (which is typically no longer than 1, at most 2 pages) rather than a detailed report with appendices of the work you've done.

Hi All,
Session 6, the first of the quant sessions, was eye-opening. Was admittedly a tad nervous because hajaar things can go wrong in such situations. The point of the quant sections is to get a good idea of what quant analysis cana nd cannot do and let the software do the rest. Hence, the emphasis on taking apart and understanding some of the technical jargon that often surrounds quant analysis.
Anyway, as expected, some stumbles and hiccups did happen.
For Sections A and B - the addendum contains details on the main reason why sample-sizing is tricky, namely that finding the sample std deviation before sampling is done is a chicken-and-egg situation. hence, the need to use past experience to guide the sigma decision and/or arrive first at an initial sample-size before iterating and arriving at the final sample size.
For section C - that SPSS failed to open was unlucky. Am hoping for better luck session 7 onwards.
For all sections - Please ensure SPSS is downloaded and ready for session 7 a day before the session starts. IT has assured me the instructions will be sent on time. If they aren't out by sunday evening, let me know.
Will conduct an R tutorial next weekend sometime. Will go over all the procedures we have covered in class on R. For the session 6 homework, folks, feel free to consult within and across groups. No problem. I'm just interested that folks ultimately find a way to do the homeworks for themselves. How you get there is upto you.

Hi,My response:
I know that the first few classes, we had to submit HW that was handwritten. But for the current Homework, it doesn't make sense to do it hand-written, as most of the work will be done in SPSS (cross-tabs, hypothesis testing).
Does that requirement of homeworks being handwritten still stand? Or can we submit a printed copy containing the tables and the statistics from SPSS?
ThanksSS,
Hi SS,
The pivots in Question are 2-by-2 tables, at most 3 by 3 ones. Am sure it'll be just as easy writing them down as copy-pasting them.
Yes, I'd like to keep the handwritten requirement continuing. It ensures that I on my part don't give out unrealistic homeworks that can't be written out in a few lines.
Regards,
