• Researchers try to maximize reliability and validity in their studies.
  
  
• Reliability refers to consistency; we should be able to obtain the same answer each time we use our measure.
  
  
• There are three types of reliability: interrater, internal consistency, and test-retest.
  
  
• Validity is whether the measurement truly reflects the concept we are studying.
  
  
• There are three common types of validity: internal, external, and construct.
