In some cases, central limit theorem is invoked such that parametric methods are said to be applicable if sample size is suitably large: "for reasonably large samples (say, 30 or more observations in each sample)... the t-test may be computed on almost any set of continuous data" [ 2].
The groups also differed in education (secondary or less was 14.7% in the KT group and 23.5% in the control group; any post-secondary was 85.3% in KT and 76.5% in control; p = 0.039) and chronic health conditions (29.8% KT, 19.1% control; p = 0.015).> -wrap-foot> ABMIeviations: BodyBody Mass Index, IQR interquartile range, N/A not applicable, n sample size, SD standard deviation.
The methodology is also applicable to sample sizes of an order of magnitude of 1 mm with currently available desktop X-ray microtomography techniques [ 22], thus exceeding that of previous attempts with at least 1 order of magnitude [ 18].
g Note that while the independent variables are not normally distributed, OLS is still applicable as the sample size is large [67].
However, when applicable, information about sample size, study design, and instrumentation were compiled.
Raw data from each array were analyzed using Multi-Class Dif (RVM-F test) which is applicable to small sample size analysis for multiple groups.
As the youth group clusters were homogenous at baseline in terms of their sexual activity, the subsequent analyses done were applicable and the sample size calculation adequately powered.
Data extracted from stream A evidence included author, year, study location, study purpose, study design, intervention type and comparison group (if any), details of the intervention (if applicable), study population, sample size, outcome measures, key results, and authors' overall conclusions.
Comparative analyses were obtained using the chi-square test for categorical data; when not applicable because of the sample size, Fisher's exact test was used.
NA: not applicable due to inadequate sample size.
