4 Column Labels All columns should be clearly and concisely labeled
Variable Name, symbol / unit and uncertainty mass, m / ± 0.5 g time, t / ± 0.02 s When there are several trials of the same variable, extend the label over all the columns

5 Ordo ab chao: sorting tables
Tables should be put in logical order according to the independent variable If there is no order for the independent variable, then sort the data by the results (dependent variable) Order may be ascending (small large) or descending be consistent with order for all tables in your report Independent variable should appear in the first column
