Results from second class experiment

Copies of all data sheets

    Columns in the spreadsheet:
  • Trial-the eight days we conducted trials
  • treat-numeric code for treatments as it was on the datasheet
  • Turb-(H)igh or (L)ow turbidity
  • Struc-(Y)es or (N)o for presence of structure
  • Tank-individual tank ID
  • n-number of remaining prey

Turb and Struc are blank for the controls.
The predator in tank I in trial 8 died during trials so we have no data there.
