First and foremost a decision has to be taken that questionnaires are the best medium to collect responses for a particular case. Interviews lower the test subject's anxiety level, making it well suited for sensitive subject matters. They may be filled with bias or the sample response could be skewed. Precision Because research subjects typically complete questionnaires without the assistance of a researcher or test proctor, it is difficult to know whether the interviewee understands the questions she is being asked. Introductory and summary questions to mark the start and end of the survey are also helpful. This is a problem as a smaller sample size may be obtained.

In particular, try to line up response boxes so that they are placed towards the right-hand side of the page. Questionnaires provide very less stability with the response processes in taking a survey. Good Evaluation Forms Before an evaluation form is distributed, make some decisions.

Open format questions: These are the type of questions that are used to allow the respondents to express their views in a free flowing manner. Open-ended questions can generate large amounts of data that can take a long time to process and analyse. Specifically, answers obtained through closed-ended questions with multiple choice answer options are analyzed using quantitative methods and they may involve pie-charts, bar-charts and percentages. It permits group administration and is adaptable to any objectives. Similarly, it is not possible to tell the seriousness of the respondent in answering the questions.
But like every other research method, a questionnaire has its own fair share of strengths and weaknesses for you to consider.
