19. Experiment Design: Example Observation: Soybean production decreased in fields adjacent to coal-powdered power plants. Hypothesis : Sulfur dioxide in high concentrations would reduce reproduction in soybeans. Experiment Design : Filtered air 0.6ppm SO2 Treated Untreated Check: 1) The number of bean pods; 2) the number of seeds per pod; 3) the weight of the pods.
20. The Dependent Variable: will be measured or counted or observed. The Independent Variable: experimental condition to manipulate The controlled Variable: keep constant or standardized Level of treatment: Replication: Control (group): Blind method: Single & double –blind Procedure: Sample size: Presenting and Analyzing Results: Prepare data table, construct graphs. Conclusion:
