Some Biases in Likert Scaling Usage and its Correction
Keywords:
Bias, difference, even, Likert scale, odd, scoring.Abstract
In this paper, common biases or errors in the construction of intervals under the Likert scaling methodology in both odd and even scales are shown. Examples of researches that uses this scales especially in survey that requires perception response from the respondents will be presented, discussed and analyzed for possible biases. Suggestions for the corrections of these biases are presented in order to minimize the bias leading for a better labeling and interpretations of the results.
