1Data Collection and Processing A Guide to Tables in IB Labs
2The Purpose of TablesTables should be organized so that others can clearly understand the data and realize relationships within the data.The data must be clearly labeled, ordered, and presented a simply as possible using as few tables as possible.Raw Data – should be presented with few processed dataProcessed Data – pooled/summary data from Raw Data table(s)
3Table LabelsHeadingTable number - for reference in the body of the report.Descriptionbriefly identify what the data isconstants used for all trials can be included herebrief notes and explanations may also be includedTable 1. Raw data of the time intervals for the PAScart to travel variousdistances down an inclined track. The slope of the incline was14.6° from the horizontal for all trials.
4Column Labels All columns should be clearly and concisely labeled Variable Name, symbol / unit and uncertaintymass, m / ± 0.5 gtime, t / ± 0.02 sWhen there are several trials of the same variable, extend the label over all the columns
5Ordo ab chao: sorting tables Tables should be put in logical order according to the independent variableIf there is no order for the independent variable, then sort the data by the results (dependent variable)Order may be ascending (small large) or descendingbe consistent with order for all tables in your reportIndependent variable should appear in the first column
