Tweet-Tag.com It's the effect size, stupid: what effect size is and why it is important It's the Effect Size, StupidWhat effect size is and why it is important Robert CoeSchool of Education, University of Durham, email r.j.coe@dur.ac.uk Paper presented at the Annual Conference of the British Educational Research Association, University of Exeter, England, 12-14 September 2002 Abstract Effect size is a simple way of quantifying the difference between two groups that has many advantages over the use of tests of statistical significance alone. 'Effect size' is simply a way of quantifying the size of the difference between two groups. The routine use of effect sizes, however, has generally been limited to meta-analysis - for combining and comparing estimates from different studies - and is all too rare in original reports of educational research (Keselman et al., 1998). The following guide is written for non-statisticians, though inevitably some equations and technical language have been used. 1. (a) (b) Figure 1 2. Equation 1 3.

How do I know I’m coding well in qualitative analysis? | Nick Hopwood Coding. Yay. Eek. Ugh. Let’s face it, coding is a biggie. But coding can be incredibly valuable to us as qualitative data analysts. Why code in the first place? If you’re coding without knowing why, and without having made a deliberate choice to do so (rather than feeling you have to), it’s not a good start. Enabling you to retrieve chunks of data, or particular phrases, quotations etc, later when you need raw data in your writing, or if you want to check ideas that come up.Helping you ‘be with’ the data in a particular way, getting you up-close to the text. What does coding well look like? Coding is a slippery slope. Good coding relates to how hard you’re thinking (and helps you think harder). But good coding isn’t purely expansive and generative. Helping you decide what data or concepts or categories to focus on, and which to set asideConsolidating what used to seem disparate or unconnected into coherent units that you can work with in whatever follows.

How Do Research Methods Affect Results? Last week, for reasons best known to one of my clients, I was reading a bunch of systematic reviews and meta-analyses. A systematic review is a way of assessing a whole lot of research at once. A researcher picks a topic, say the effectiveness of befriending services in reducing the isolation of housebound people, then searches all the databases they can for relevant research. That usually yields tens of thousands of results, which of course is far more than anyone can read, so the researcher has to devise inclusion and/or exclusion criteria. Some of these may be about the quality of the research. Does it have a good enough sample size? These decisions are not always easy to make. One of the systematic reviews I read last week reported an earlier meta-analysis on the same topic. Randomised designs are at the top of the hierarchy of evidence. Now don’t get me wrong, I’m not anti-RCTs. This is troubling me and I have more questions than answers.
Durham University Evidence Centre for Education (DECE) : DECE latest news 'A virtual free-to access journal of 20 years of research by Stephen Gorard' Professor Stephen Gorard has collected together open-access links to some of the hundreds of peer-reviewed journal articles and research reports he has written so far with a range of valued colleagues, in recognition of the increasing number of peer-reviewed papers becoming freely and openly available to all, either because of new journal designs, or because research funders pay for ‘gold’ open access, or university repositories, and of the benefits of such availability of information for potential readers and consumers of research, such as policy-advisers, think tanks, unions and practitioners. The document can be found under 'Resources' on the right hand column of this page and under 'Resources' at the bottom of out our 'Publications' page.
