About this printable
Plan the structure of a data table before collecting observations. The worksheet helps learners decide what one row represents and where each unit belongs.
How to use it
For a classroom plant-height activity, one row might represent one plant on one date. Write headings that distinguish the plant identifier, date and height in centimeters. Try one imaginary entry to see whether another reader could interpret it without an explanation.
Check and adapt
Keep numerical values and descriptive notes in separate columns when that makes comparison easier. Define any short codes and decide how to mark a missing observation. Do not use zero to mean missing unless zero is genuinely the measured result.
