Questions and answers
Scientific data table template FAQ
What should a scientific data table include?
A scientific data table should include a descriptive title, variable names, units, trial columns, measured values, calculated values, and relevant observations.
Where should units be written in a data table?
Units should normally be included in the column or row headings so they do not need to be repeated in every data cell.
Why should repeated trials be recorded separately?
Separate trial values reveal variation, make anomalies easier to identify, and allow averages or ranges to be calculated.
Should unusual results be removed from the table?
No. Unusual results should remain recorded and should be investigated and explained before any justified exclusion.
