WebFeb 7, 2015 · Table 1 given below is the Reliability Statistics Table which provides the value for Cronbach alpha which in this case is .805 and reflects the high reliability of the measuring instrument. Furthermore, it indicates a high level of internal consistency with respect to the specific sample. WebValidity and reliability evidence is presented for the Vowel Matching Test (VMT), an instrument that measures primary grade children's ability to discriminate medial vowel sounds. The VMT consists of a series of seven picture sets, each set containing a stimulus picture and three item pictures. Based on the responses of 43 first-grade pupils ...
Reliability vs. Validity in Research Difference, Types and Examples
WebThe third approach to reliability, i.e., the internal consistency, uses only one administration of an instrument or test to assess the consistency or homogeneity among the items. It must always be kept in mind that the reliability refers to a specific measuring instrument applied to a specific population under a specific condition. WebFor research purposes, a minimum reliability of .70 is required for attitude instruments. Some researchers feel that it should be higher.
