In this paper, the term "invalid answer" (IA) means such choises as "sono ta" (NAC: there is no appropriate choice) and "wakaranai" (DK: don't know), as well as "no answer". From the NFR98 questionnaire, 50 questions are subjected to scrutiny because they are applied for all of the sample. Findings are as follows:

  1. 3,214 cases (46% of the valid sample) have IA.
  2. There are some districts where both valid reception and IA show high rate.
  3. Those who have such characteristics as follows show high IA rate:
  4. Questions offering NAC/DK choices tend to create IA.
  5. Canvasser's checks at the picking up the questionnaire reduce the probability of IA occurance.
  6. Same kind questions consist a sequence show correlations in IA occurance.
  7. Education have the effect of reducing IA on the all 50 questions.

Based on the findings, this paper mentions to caution in analizing NFR98 data, and to modifications to similar surveys in future.

Key Words: missing data, no answer, non-sampling error
