The right question type and format can make a big difference in how your respondents answer your market research questions. Depending on your research objectives and the type of data you want to collect, you can choose from different question types, such as open-ended, closed-ended, multiple choice, rating scale, ranking, or matrix. Each question type has its own advantages and disadvantages, so you need to consider the trade-offs between the depth and breadth of information, the ease and speed of response, and the analysis and interpretation of data. For example, open-ended questions can provide rich and detailed insights, but they are harder to answer and analyze. Closed-ended questions can provide quick and standardized data, but they may limit the range of responses and miss some nuances. You also need to pay attention to the format of your questions, such as the order, length, wording, and layout, to ensure they are consistent, logical, and easy to read.
