Assuming an attrition rate of 12%, we estimated a target sample size of 211 articles. We considered this set of 7 journals to comprise a representative sample of the top-tier general public health literature. Visual displays of data in the form of charts, figures, or graphs, were reported in 61.6% (n = 133) of the articles. No, Is the Subject Area "Statistical methods" applicable to this article?

Topics covered include the choice of appropriate averages and measures of dispersion to summarize data sets, and the choice of tests of significance, including t-tests and a one- and a two-way ANOVA plus post-tests for normally distributed (Gaussian) data and their non-parametric equivalents. However, these techniques, as well as complex statistical modeling techniques such as structural equation modeling and factor analysis, were rarely applied and reported.
