Significant effect on primary productivity

Assignment Help Biology
Reference no: EM132510626

Is there a flaw in this experiment?

The scientist fertilizes one lake with phosphorus and takes 50 water samples 1 month later to determine the amount of chlorophyll in the lake. The scientist also takes 50 samples from a control lake of the same size. The average chlorophyll level is significantly higher (p<0.05) in the fertilized samples than in the control samples, so the scientist concludes that phosphorus has a significant effect on primary productivity.
