  Data Analysis Issue Example
(a) Observations from a single expert “Charlie” recalls schools of hundreds of paku‘iku‘i (Achilles tang) in Kaloko in the 1960s, but for the last decade (1996 to 2006) has counted no more than a dozen at any given time
(b) Observations from multiple experts “Elaine” recalls schools of hundreds of paku‘iku‘i in Kaloko in 1960s, while “Barry” counts no more than one dozen of the fish in the same area today (2006).
(c) Quantitative abundance “For decades we would see between 10 and 13 lionfish on any given dive in that area. Then, they all disappeared, and we haven’t seen one since.”
(d) Relative abundance “Yellow tang schools were like rivers of yellow, or beds of yellow tulips until the 1980s, then noticeably in decline until the late 1990s when you might see two or four fish in any area”
(e) Relative abundance (Indicating a change catch per unit effort) We used to go spearfishing and all would choose a fish and only take that one kind of fish. I’d take manini (convict tang) my friend would take uhu (parrotfish)... There used to be so many fish, I would have to push them out of the way to get the one I wanted. After an hour, our lines would be full. Now a couple of hours, and you get only a couple fish, different kinds. Last week, I got in the water, and I was excited to see one fish. Just one fish!”
(f) Distribution Tinker’s butterflyfish have been observed historically (1930s) from 5 to 180 feet depth. But for some decades adult Tinker’s have not seen shallower than 100 feet. This is an indication of a relative decline in distribution over space (shallow depth range) and time (recent decades).
