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.
