Take your time and do it again
Use a ruler instead of a tape measure
Ask someone else to measure for you
Measure as quickly as possible
Why is accuracy described as being "based on what YOU do"?
Because accuracy depends on your actions and how carefully you measure
Because accuracy is determined by the weather
Because accuracy is only important in sports
