What are two primary disadvantages of mail questionnaires
Two primary disadvantages of mail questionnaires are:
- Low Response Rate: Mail questionnaires often have a low response rate, which can be a major limitation. This is because respondents may not take the time to complete the questionnaire, or they may not be interested in participating. This can lead to a biased sample, which may not accurately represent the target population.
- Limited Data Quality: Mail questionnaires can also suffer from limited data quality due to the lack of immediate feedback and interaction with the respondent. This can lead to errors, inconsistencies, and missing data, which can be difficult to correct. Additionally, respondents may not fully understand the questions or may not provide accurate answers, which can impact the validity and reliability of the data.
These limitations can be mitigated by using other methods, such as online surveys, phone surveys, or in-person interviews, which can provide more immediate feedback and interaction with the respondent.
