Especially when said points are spaced at near five year intervals. I work as a Manufacturing Engineer, and spend a good deal of time analyzing in-process data in order to assess trends and potential modes of product failure over time. If I ever went to our Quality Engineering team with the limited data I see in the OP, you can believe I'd have a hard time being taken seriously. |
Yeah, a pattern spaced 20 years apart is not enough to be called a trend. Lol.
You act is the data is JUST every 5 years. But the fact remains that the 5 years is comprised of yearly sales, monthly sales, weekly sales and daily sales. Which, obviously if the sell less every 5 years means they sold less yearly during those 5 years too.
