Document Summary
Measure the dimensions of beach in m2 . Estimate sample unit size size of quadrat to fit 25 of the largest clam . Use random numbers to select sites for quadrat . Always stay consistent with use of quadrat . Count clams by species, record, go to next beach and repeat . Determine if there is a difference in density between shells found on the two beaches . Compares observed frequency with expected frequency for each species . Histograms; use of randomization; random number table . Plotting normally distributed data on a histogram will form a bell shaped curve . Done in order to ensure sampling is not biased . Quadrat placement based on numbers in table . Use of bod bottles; winkler titration . Light bottles = clear, allow light, photosynthesis . Dark bottles = black, do not allow light, no photosynthesis . Initial water do level read, and final db and lb water do levels read .
