Even-point or odd-point measurement scales

Even-point or Odd-Point Measurement Scales Introduction A manufacturer may conduct research to introduce a product inthe market by use of questioners and employ either Likert Scale or Semantic differential scale. Either can be an odd point or even point scale.
Merits of odd-point
It provides the respondent with a range of option including where the defendant can remain neutral. It is advantageous, as the respondent is not put in an awkward situation where he/she must give an answer from either of the extremes. However, respondent may not be in either extreme. Secondly, it removes the prejudice against one extreme, as there is a neutral position (Penwarden, 2014).
Merits of Even-Point
it does not provide a neutral position, and the respondent must take a position. It is advantageous when dealing with two different products that you want to choose from (Penwarden, 2014).
Recommendation
Odd-point is in conducting market research on carbonated and non-carbonated energy drinks. This is because it will eliminate the bias of a respondent giving a response either for or against both drinks only.
