- soared 10y agoExactly! Who in their right mind would deliver a report to their boss and say, "Its only been a couple days, but this drastic change has been successful!" But someone instead went to the NYT and said that same thing.
- busterarm 10y agoGee, I wonder if Chase buys display ads on NYT...
- bigtimeidiot 10y ago>I think this fact alone invalidates the data It invalidates the data? How so? Or do you mean conclusion? Even so, there's nothing inherent with "a few days" that makes the analysis invalid due to sample size; that depends on the nature of the data. In my employment we are measuring changes hour to hour.
- bluGill 10y agoBecause advertising is about perception. If I see chase ads every day will remember them in 6 months when I suddenly realize I need a new credit card - today I'm happy with my card selection and no amount of advertising will get a bite from me, but when that changes I might change to a "lesser" card just because I didn't think to check chase out. thus they need numbers over months before they can state it worked.
