  8. EXPEIMENTAL TRADE-OFFS • generality versus confidence • realism versus control • replication versus cost • complexity versus control and cost

  9. Experimental Design • Control • Random sampling • Replication • Sample size

  10. Experimental Design • Control • provide a comparison • Random sampling • Replication • Sample size

  11. Experimental Design • Control • provide a comparison • Random sampling • avoid bias • representative sample • Replication • Sample size

  12. Experimental Design • Control • provide a comparison • Random sampling • avoid bias • representative sample • Replication • control for unknown variables • quantify variance • Sample size

  13. Experimental Design • Control • provide a comparison • Random sampling • avoid bias • representative sample • Replication • control for unknown variables • quantify variance • Sample size • increase power

  14. Refine the research objective

  15. Refine the research objective • Determine Treatment(s) • one treatments with control • multiple treatments‘ with control • gradient of treatments with control

  16. Refine the research objective • Determine Treatment(s) • one treatments with control • multiple treatments' with control • gradient of treatments with control • Determine Response(s) • number of responses • measured versus counts • what the data will ‘look’ like

  17. Refine the research objective • Determine Treatment(s) • one treatments with control • multiple treatments' with control • gradient of treatments with control • Determine Response(s) • number of responses • measured versus counts • what the data will ‘look’ like • Determine Appropriate Analysis • number of treatments • nature of the data • question asked
