Questionnaires are one of the most popular data collection methods for quantitative studies. They involve the use of pre-defined questions or statements to gather responses related to the phenomenon being studied. With questionnaires being so important and highly in-demand, many researchers find themselves opting to utilize this tool as their research instrument. You can either use a standard questionnaire that is available for your study or prepare your own. However, most of the time, a standard questionnaire that is suitable for your study may not be available for use.
Therefore, you might need to prepare your own questionnaire. Formulating your own questionnaire design in such a way that the instrument will be reliable, valid and collect all the information that you need can be challenging. That is why Rehoboth Academic Services offers unique services targeted at questionnaire preparation. Our team of experts is trained at offering you support in all aspects of creating a tailor-made questionnaire, to help make your data collection as efficient as possible. The research instruments that we help you to prepare are literature based, to ensure the best quality of results.
What types of survey questions do Rehoboth Academic Services prepare?
- Closed-ended questions – Closed-ended questions are extremely useful for quantitative studies, in terms of coding the data and analyzing it. When such questions are used, the respondent selects the response from options that are provided to them. The different types of closed-ended questions that we employ include:-
- Likert-scale based questions
- Nominal questions
- Ordinal questions
- Ranking questions
- Open-ended questions – We also incorporate open-ended questions that allow the respondent to fill in their own thoughts and opinions. These items are useful to obtain information for descriptive studies and for qualitative assessments.
All questionnaires are prepared according to existing available literature sources. We don’t have readymade interview questions and answers.
Sample Size Calculation
When conducting a research study, selection and calculation of the sample size is crucial to the success of the outcome. A sample is a portion of the total population that has the same characteristics as the entire population, making it representative of the whole.
Why Is Sample Size So Important?
Your sample size has to be just right, not too big and not too small. If your sample is too small, it may not be truly representative of the population that you want to study, implying that your findings will not be as useful as they could be. If your sample size is too large, then measuring the desired phenomenon will consume more resources than is ideal for the study.
