• framework for research planning and answering research questions


  research design
• complete sequence of steps that will be undertaken in a project

  research design
• 3 basic elements of research design

  1.) Identification of variables

  2.) Application of basic research principles

  3.) Consideration of the research design structure
• main material being used/studied


  subject
• also known as "experimental unit"


  subject
• any procedure done on the subject

  treatment
• effect is measured and analyzed

  treatment
• a group of homogeneous subjects

  block
• controllable IV that is thought to influence the respone

• 3 classifications of variables

  1.) Independent

  2.) Dependent

  3.) Extraneous
• test sample or group that receives an experimental procedure


  experimental group
• group that is separated from the rest of the experiment

  control group
• 4 basic principles of research design


  1.) Local control

  2.) Replication

  3.) Randomization

  4.) Control of extraneous variables
• balancing, grouping, and blocking of subjects


  local control
• 2 techniques in local control
