Systematic error
error due to the equipment accuracy or set up, ‘consistent’, cannot be averaged out
Random error
caused by human ability, different each time, can be averaged out, given by half the smallest division.
Accuracy
How close results are to the true value
Precision
a measure of how consistent you can be with your measurements
Tables should:
Plan the correct number of columns and rows to avoid adjustments later.
Use a ruler to create neat, straight lines.
Label columns and rows clearly with quantities and units (e.g., Temperature / °C) using slash notation to keep table values unitless.
Maintain consistency in significant figures.
For calculated differences, include initial, final, and difference values.
Add columns for simple conversions, like inverting or scaling.
