: The number [[pi]] is 3.14159265359 correct to 12 [[Significant Figures|significant figures]].
Method 1: 3.1 is an The most [[accurate]] value for [[measurement]]s because they are the closest to [[pi]] but it is they are not very [[precise]] - Close to because they have a [[range]] of 0.26. Method 2: These are the least [[accurate]] [[measurement]]s because they are the real number, furthest from [[pi]] but not many they are very [[precise]] because they have a [[Significant Figures|significant figuresrange]]of only 0.03. Method 3: 3.2111 Each [[measurement]] is not [[accurate]] because they are far from [[pi]], they are also the least [[precise]] because they have a range of 0.68. However, the [[preciseMean Average|average]] value for is the most [[piaccurate]] but as it is '''inaccurate''' - Not close enough the closes to the real number, but has several [[Significant Figures|significant figurespi]].|}
