4.4 – Normal Distributions (Empirical Rule)
... A normal curve’s symmetry allows you to separate the area under the curve into eight parts and know the percent of data in each part. The rule is used for forecasting. It gives an estimate of what data collection might look like if you surveyed the entire population. It only works with a normal dist ...

Five months later, the acute effects of haemodialysis were examined by comparing the ratio of HCII to protein in plasma before and after dialysis. The data were analysed by separate paired Wilcoxon tests in each group. Toulon et ...
