My sampling strategy was haphazard because I tried to show a gradient of flow rates. So I tried to choose areas with slow, moderate and high flow rates. This was effective but could be more effective and less biased if I implemented a simple random sampling technique. The data I collected was pretty consistent with what I expected but one surprising thing was I found the Chara algae in low flow areas where I hypothesized I would only find chara in high flow areas. I am going to change my sampling strategy to simple random. I think I will do this by flipping a coin to decide whether to go up or downstream and then picking a random number between 3-16 to decide how many paces up or downstream to walk. I think this will give results that are more accurate and less biased on my part.
