Another interesting article! Check this other post from +Tsvetan Vuchkov
Is mastering statistics or mastering the basic concepts (time & context) like this article states more important?
Which do you think it should be a priority?
I think it depends on your background - I often use a triangular shape to explain the areas of expertise: business, enabling technologies, and analysis. If you are more inclined toward analysis and have a statistical background, then you see the world with lenses that makes you think everyone should know about standard deviation, margin of error and confidence intervals... (and this type of person usually freak out about GA sampling or not being able to have the raw data to check if the tool is right!).
If you are more of the marketer type - more inclined toward the business side of things, then putting data in context (such as the article you refer too) might be a more important skill. In my graduate-level class I showed the stats from +Save the Children USA
where there was a huge spike of traffic, about 20% of the students actually take time to relate the data to the context (i.e. a earthquake, a disaster somewhere, war... a big announcement, something "external" to the website itself) while most will simply talk about the volume of traffic, the average, high/low and things like that... guess which one would be the analyst I want?
The "enabling technologies" aspect relates to instrumentation, data structures, web/mobile technologies... anything that turns the "business" vision into reality...
