Survey is done for so many reasons. If the survey questionnaire is not prepared well (consisting of long and vague questions), the respondents get bored, lose their interest and throw the survey questionnaire into the trash. If you wish to complete your survey, you should know how to compose survey questions to make people comfortable in answering the questions which will provide you the results which you need.
Purpose of the survey
You should decide about your purpose of your survey and make it clear to the audience. Before you compose your queries, write down what you exactly want from the respondents and what extra information would be beneficial. Refer this while preparing your survey questions. On the top of your cover letter or survey, mention the survey purpose and include a date on which you need the respondents to return you back. Make your survey questionnaire clear.
If you want to make your survey successful, keep your survey short and your questions clear and precise. Each query should discuss about one issue.
Multiple choice queries are simple to answer and also to analyze for the required information. Provide enough options to cover every possible answer.
Do not add the queries with any kind of unclear adjectives. Use only precise words. Avoid using abbreviations which the respondents may not know. Always remember to maintain your survey clear and precise.
If you want to include a rating scale, ensure that there are 2 extremes for the answers. Explain those extremes clearly when you use modifiers. Than the rating scale, multiple choice queries will be much clear.
Testing the survey
Finally, you can test the survey by providing it to some people to fill it out. You can ask them about questions, whether they are confusing or clear. If you maintain your survey simple, anonymous, clear, short, focused and precise, your survey will be successful.
