Likert (1967), Lankford (1994) and Veal (1997) list the advantages of the Likert method as including:
1- the fact that the method is based entirely on empirical data regarding subjects'
responses rather than the subjective opinions of judges;
2- the fact that this method produces more homogeneous scales and increases the
probability of a unitary attitude being measured; as a result, validity (construct and
concurrent) and reliability are reasonably high; and
3- greater ease of preparation.
