Within a margin of error the measurement is consistent across instruments and observers. Consistency (don"t contradict to each other), coherence(speak the same language) and convergence(independently came to the same result ah as markers or reality. In order to check for son sisterly and coherence, we need to be able to compare different results according to the same measures. Statements that describe the procedure(or operation) and specific measures that are used to record observation. Different definitions - come to a completely different conclusion from the hypothesis. Defines the same words in a different fundamental way. E. g. , shyness = infrequent communication or contact with others (doesn"t want to connect) Shyness = high anxiety in the presence of others (wants to connect but finds it difficult) Measurement validity: the degree to which an instrument or procedure actually measures what it claims to measure.
