If you have ever read a student thesis on anxiety, you have almost certainly met the GAD-7. It is short, free, and trusted by researchers around the world — which is exactly why supervisors keep recommending it. But a seven-item questionnaire still raises practical questions: how do you score it, what do the numbers actually …
What Is Grounded Theory? Imagine you are studying how first-year PhD students cope with the pressure of their new life. You have no hypothesis to test and no ready-made theory that quite fits what you are seeing. Instead of forcing your data into someone else’s framework, you collect interviews, look closely at what people actually …
Being asked to critically appraise a research paper can feel intimidating, especially the first time. You are not being asked to decide whether the paper is “good” or “bad” in some vague sense. You are being asked to judge, step by step, whether the study was done well enough, whether its results can be trusted, …
If you have ever filled in a questionnaire that asked you to rate statements from “Strongly disagree” to “Strongly agree”, you have already used a Likert scale. It is the most common way researchers measure attitudes, opinions and perceptions — and yet it is also one of the most commonly mishandled parts of a student …
Introduction If you have ever sat in front of twenty open PDFs, a half-written literature review, and the sinking feeling that you have read everything but remember nothing, you are not alone. That is the moment most students discover they needed a system — not more reading. A literature review matrix is that system. It …
Imagine you run a survey to find out whether students like your university’s new online library. You ask: “Don’t you agree that the new online library is a huge improvement?” Most people say yes — and you walk away thinking the library is a hit. But did you actually measure their opinion, or did your …
A questionnaire looks simple. A list of questions, a link, a few hundred responses — and then the trouble starts. Answers that contradict each other, half-finished surveys, and results you cannot quite trust. In most cases, the problem is not the sample size or the statistics. It is the questionnaire itself. Good questionnaire design is …
What Is a Meta-Analysis, and Why Does It Matter? If you have ever read five studies on the same question and found five different answers, you already understand the problem a meta-analysis solves. One study says an intervention works brilliantly. Another finds almost no effect. A third sits somewhere in between. Which one should you …
If you have ever been told to “do a systematic review” and felt your stomach drop, you are not alone. A systematic literature review sounds like one of the biggest, scariest assignments in research — and honestly, it is a big job. But it is not a mysterious one. It is simply a literature review …
Missing data is one of those problems almost every researcher meets, and almost nobody plans for. You collect your questionnaires, open your spreadsheet, and there it is: blank cells where answers should be. A few students skipped the income question. Three respondents left the last page blank. One interview ended early. It is tempting to …
