... The Summarize procedure calculates subgroup statistics for variables within categories of one or more grouping variables. All levels of the grouping variable are crosstabulated. You can choose the order in which the statistics are displayed. Summary statistics for each variable across all categories ...

Statistics Notes
... Finding the limits As a “rule-of-thumb”, if not specified, use +/1/2 of the smallest measurement unit (ex metric ruler is lined to 1mm,so the limit of uncertainty of the ruler is +/- 0.5 mm.) If the room temperature is read as 25 degrees C, with a thermometer that is scored at 1 degree intervals ...
