What two things do all measurements must consist of?
A number and a unit
What is the standard formula for calculating the mean for a set of measurements?
Add all of the measurements together and then divide that sum by the number of measurements to get the mean. Example: (2,2,3,5,7,9). 2+2+3+5+7+9= 28. Then 28 divided by 6 (the number of terms) = 4.666 or 4 2/3
