Confidence limits and statistical significance are involved in generalizing from the observed value of an effect to the true value of the effect. The true value of the effect is the average value of the effect in the whole population, or the value of the effect you would get if you sampled the whole population. The confidence limits of an effect define the likely range of the true value of the effect: in short, how big or positive and how small or negative the effect could. An effect is statistically significant if the likely range of the true value of the effect is unlikely to include the zero or null effect. Roughly speaking, statistically significant effects are unlikely to be zero, but such a rough interpretation is misleading: in sport and exercise science, the true value of an effect is never exactly zero. Statistical significance is notoriously difficult to understand, whereas confidence limits are at once more simple and more informative.

Cite the reviews and indicate the extent to which you have based your review fairy on them. Make sure you look at the key original papers cited in any earlier reviews, to judge for yourself whether the conclusions of the reviewers are justified. Reviews, like original research, vary in quality. Problems with reviews include poor organization of the material and lack of critical thought. Some of the better reviews attempt to pull together the results of many papers using the statistical technique of meta-analysis. The outcomes in such reviews are usually expressed as relative risk, variance explained, or effect size, terms that you will have to understand and interpret in your review if you meet them. See my statistics pages for explanations of these concepts (. Interpreting Effects, you cannot assess quantitative research without a good understanding of the terms effects, confidence limits of effects, and statistical significance of effects. An effect is simply an observed relationship between variables in a sample of subjects. An effect is also known as an outcome.
There are big differences in the way data can be collected. At one extreme are qualitative methods, in which the researcher interviews subjects without using formal psychometric instruments (questionnaires). At the other extreme are quantitative methods, in which biological or behavioral variables are measured with instruments or techniques of known validity and reliability. In the middle are techniques with uncertain precision and questionnaires with open-ended responses. Qualitative assessment is essay time consuming, so samples are usually small in size and non-representative, which in turn limit the conclusions that can be made about effects in a population. The conclusions may also be biased by the prejudices of the researcher-interviewer. Quantitative data collection is more objective, but for some projects it could miss important issues that would surface in an interview. A combination of qualitative methods for pilot work and quantitative methods for a larger study should therefore produce valuable conclusions, depending, of course, on the design. You will probably find that your topic has been dealt with to some extent in earlier reviews.
The most trustworthy conclusions are those reached in double-blind randomized controlled trials with a global representative sample of sufficient size to detect the smallest worthwhile effects. The weakest findings are those from case studies. In between are cross-sectional studies, which are usually plagued by the problem of interpreting cause and effect in the relationship between variables. How subjects were sampled table is an important issue. You can be confident about generalizing results to a population only if the sample was selected randomly from the population and there was a low proportion of refusals and dropouts ( 30). Be wary of generalizing results from novice athletes to elites. Something that enhances performance in young or untrained individuals may not work so well in highly trained athletes, who may have less headroom for improvement.
(1979) and Smith and Brown (1987)." Describe and justify briefly any papers or areas that you decided not to include. Findings, this section is the most important part of your review. Do not give a summary paper-by-paper; instead, deal with themes and draw together results from several papers for each theme. I have identified four themes for this section: assessing the quality of published work; interpreting effects; points of grammar and style; and a few remarks about tables and figures. These themes are dealt with under subheadings. I encourage you to use such subheadings, which will make it easier for you to write the review and easier for others to read. Quality of Published Work, look critically at any published work. The fact that something has been published does not mean the findings are automatically trustworthy. Some research designs are better than others (see.
