What is an outlier

• something very different from the rest of the data

• something very similar from the rest of the data

• another name for best value

• another name for uncertainty

Average

• best value

• uncertainty

• multiple trials

• outlier

How to calculate the range

• trial 1 + trial 2 + trial 3 / 3

• highest value - lowest value / 2

• best value - the uncertainty, best value + the uncertainty

• trial 1 + trial 2 + trial 3 / 2
