Sketch the boxplot and annotate it with the 5 numbers and IQR:





Outliers (by the <,> 1.5*IQR method):______________________

2*s=_______  mean-2s=______  mean+2s=_____
Which datums are "statistically significant"___________________
 i.e. not within 2 SD of the mean == More than 2 SD from the mean.

Looking at the sorted data and the frequency distribution table,
does the data appear to be measured or self-reported, rounded, averaged:
