Questions tagged [likert]

Classically, a Likert scale was composed of the sum of many Likert items (ordinal ratings of the amount of agreement with a statement), where all the items were equally valid. Today the term sometimes is used synonymously with 'ordinal rating scale' (which may be based on only 1 item).
