- I just realized something. We could have set the spectrometer to -2, and that would have allowed us to read values that had phosphorous readings up to 4 mg/L, and then our data wouldn't have been so messed up.
- So now, all we are waiting for is the duckweed amounts, which Taylor has.
BTW, it seems that even though we screwed up, everything worked out alright, and we can see a trend (phosphorous decreases as duckweed increases.) I obtained the actual values by using the control, assuming that it should have stayed at 5 mg/L, yet the reading showed .210. Therefore, I multiplied all the other phosphorous readings by 5/.210 to get their actual values (hopefully that works).
- The final column shows what the values would have been if we had done the experiment correctly, and if the spectrometer actually went up that high.
