Quantitative research involves measuring and counting data to precisely reflect the situation being studied. Questionnaires are a popular tool that can be used for quantitative research. Developing an effective questionnaire involves defining the problem, using previous studies and expert advice, defining research objectives and questions, determining sample size, developing and pretesting the preliminary questionnaire, including a cover letter and follow-up for non-respondents. Questionnaires have advantages like broad coverage, economical for large populations, and collecting quantitative data, but also disadvantages like low response rates and inability to uncover causes of attitudes.
