A Likert scale is considered a quantitative measurement tool because it assigns numerical values to responses and allows for numerical analysis of data.
A Likert Scale Questionnaire is one where the subjects are asked to mark how much they agree with the point of view in the item. Rensis Likert devised it first. An item in a Likert Questionnaire could be "People who commit murder should be executed." The format for a five-point Likert scale could be: # Strongly disagree # Disagree # Neither agree nor disagree # Agree # Strongly Agree The results are either analyzed separately, or the whole scale may be totalled or summed. Because of this, Likert Scales are often called "Summative Scales".
