In our daily lives in Ghana, people are always trying to find out information. A market woman wants to know what her customers like best. The headteacher wants to know which subjects students enjoy. A TV station wants to know the most-watched programme. How do they get this information accurately from many people? One of the most powerful tools they use is a questionnaire. This lesson will teach us how to become researchers by creating our own questionnaires to find answers to questions that matter to us, our school, and our community. This is a very practical skill used in business, governance, and even in planning fun events like "Our Day"!
A. What is Data? Data is simply a collection of facts, such as numbers, words, measurements, or just descriptions of things. When we collect data ourselves directly from people, it is called primary data. A questionnaire is one of the best ways to collect primary data. B. What is a Questionnaire? A questionnaire is a list of written questions used to gather information from a group of people (called respondents). Think of it as a structured conversation on paper. The goal is to get answers to a specific problem or topic. Example: If we want to find out the most popular mobile network among teachers in our school, we can create a questionnaire and give it to them to fill out. C. Types of Questions The questions you ask are the heart of your questionnaire. There are two main types: Closed-ended Questions These questions give the respondent a limited set of options to choose from. They are easy and quick to answer, and the data is easy to count and analyse. Yes/No Questions: *Do you own a smartphone? ( ) Yes ( ) No* Multiple Choice Questions: *Which is your favourite local dish? (Please tick only one)* ( ) Waakye ( ) Jollof Rice ( ) Kenkey with fish ( ) Fufu with soup Rating Scale Questions: *How much do you enjoy Mathematics? (Circle one number)* 1 (Not at all) - 2 (A little) - 3 (It's okay) - 4 (I like it) - 5 (I love it!)
When to use them: Use closed-ended questions when you have a good idea of the possible answers and you want data that is easy to turn into a chart or graph. Open-ended Questions These questions allow the respondent to answer in their own words. They provide more detailed and personal information. Examples: *"What do you like most about our school?"* __________________________________________________ *"What suggestions do you have to improve the inter-house sports competition?"* __________________________________________________
When to use them: Use open-ended questions when you want to explore new ideas or understand the reasons *why* people have a certain opinion. D. Steps to Design a Good Questionnaire
A good questionnaire is like a good recipe; you must follow the steps carefully.
