OBJECTIVE Prior research has found that within-person standard deviations across different neuropsychological domains are larger in various clinical groups than in healthy control groups, but little is known about the specificity of these measures to clinical conditions. METHOD Within-person standard deviations were computed across composite scores representing episodic memory, perceptual spe...
The Effects of “ Girl - Friendly ” Schools : Evidence from the BRIGHT School Construction Program in
We evaluate a “girl-friendly” primary school program in Burkina Faso using a regression discontinuity design. After 2.5 years, the program increased enrollment by 19 percentage points and increased test scores by 0.41 standard deviations. For those caused to attend school, scores increased by 2.2 standard deviations. Girls’ enrollment increased by 5 percentage points more than boys’ enrollment,...
A model independent analysis has been performed on the LEP and SLD data on Z decays. Using only very weak theoretical assumptions, the effective vector and axial-vector couplings of leptons, c quarks and b quarks have been extracted. Although the lepton and c quark couplings agree well with Standard Model predictions, those of the b quark show deviations of more than three standard deviations. ...
The relationships of ranges to their respective standard deviations for wind direction and speed fluctuations are found for two urban locations at a height of 33 f t . above ground level. The standard deviations are computed from 1-, 5-, lo-, and 15-sec. average and 5-, lo-, and 15-sec. iiistantaiieous chart readings. The sampling intervals for which the standard deviations and ranges are compu...
Consequences of multiple imputation of missing standard deviations and sample sizes in meta‐analysis
Meta-analysis, power analysis, and sensitivity analysis are widespread statistical techniques, which can be correctly performed only if variability statistics, such as standard deviation, available; however, deviations often missing in published articles. This work illustrates the functionality versatility of a newly developed Excel© tool for deviation extraction from ANOVA Multiple Comparison ...
