... The mean birth weight was 3.627(3.428;3.825) kg among nonsmokers compared to 3.174(2.907;3.442) kg among heavy smokers. The difference 452(138;767)g was statistically significant (p=0.06%). Conclusion: Children born by heavy-smokers have a birth weight, that is statistically significantly smaller, t ...

The Median is the Message
... the “standard deviation” of the median to the next section. Since there appears to have been no generally agreed upon method for assessing the accuracy of the median at the time, these entries are one of the more intriguing aspects of the analysis. The scale estimates in Columns 3-6 of the table are ...

Significance/Hypothesis Testing
... consequently, the two methods are often confused. In hypothesis testing, the underlying model (Step 1), the null and alternative hypotheses (Step 2), and the test statistic (Step 3), are formulated exactly the same way as in significance testing. The first difference arises in the design step (Step ...
