  Previous research studies
  Data collection mode. The method of data collection determines the appropriate response format.
  Ability of the respondent. Some respondents may relate better to one type of response format than another.
  Scale level desired. If a researcher desires to use higher-level statistical analysis, the question’s response format must be corresponding.

  Scale characteristics are:
  Description – refers to the use of a unique descriptor, or label, to stand for each designation in the scale.
  Order – refers to the relative sizes of the descriptors.
  Includes such descriptors, as “greater than”, “less then”, “equal to”.

  A scale has the characteristic of distance when absolute differences between the descriptors are known and may be expressed in units.
  
  A scale is said to have the characteristic of origin if there is a unique beginning or true zero point for the scale.

  Issues in the use of sensitivity scales
  Using scaled-response formats requires the researcher to confront 2 issues.
  Whether or not to include the middle, neutral-response option.
  
  What are the arguments for and against the inclusion of a neutral response position in a scale?
  2. Is there a need to have a completely symmetric scale?

  Reliability and validity of measurement
  Ideally, a measurement used by a market researcher should be reliable and valid.
  Picture a bull’s eye target with several bullet holes clustered very close together, but off the center of the target. This is reliability: the rifle was pointed at the center, but bullets were consistently off-center and in one spot. When the rifle sights are aligned so that the bullet hits dead center when the rifle is aimed there, it is valid. If the holes are consistently in the center area, the sight is valid and reliable

  Measurement in Marketing Research - Case.
  Case 6.1. Mike, the owner of Mike’s Market, which is a convenience store, is concerned about low sales. He reads in a marketing textbook that the image of a store often has an impact on its ability to attract its target market. He contacts the All-Right Research Company and commissions it to conduct a study that will shape his store’s image. You are charged with the responsibility of developing the store image part of the questionnaire.
  Design a semantic differential scale that will measure the relevant aspects of Mike’s Market’s image. In your work on this scale, you must do the following: (a) brainstorm the properties to be measured, (b) determine the appropriate bipolar adjectives, (c) decide on the number of scale points, and (d) indicate how the scale controls for halo effect.
