Understanding Likert Scale Levels
At the core of a Likert Scale are levels that allow respondents to indicate their agreement or disagreement with a statement. The most common Likert Scale has five points, but other variations with more points are also used. Here is a breakdown of the five-point Likert Scale:
Strongly Disagree: This option represents a strong negative response, indicating the highest level of disagreement with the statement.
Disagree: A step above “Strongly Disagree,” this choice signifies disagreement with the statement.
Neutral: The middle point on the scale where the respondent is neither in agreement nor disagreement.
Agree: This indicates agreement with the statement.
Strongly Agree: The highest positive response, signifying strong agreement with the statement.
The seven-point and ten-point Likert Scales offer more nuanced responses, allowing for better differentiation between subtle differences in attitudes.
