WebbAs α is nearly constant and also very small, for practical purposes, we use the linear approximation: Δ L = α L Δ T 1.2 where Δ L is the change in length and Δ T is the change in temperature. Table 1.2 lists representative values of the coefficient of linear expansion. WebbStep 2:Calculate the square of each sample minus the mean. Step 3:Sum all those squares for all measurements. Step 4:Divide the sum by N and take the square root. Step 5:State the final measurement. Example: Calculate the standard deviation with the equation above The following measurements are given: 5.4 6.7 3.8 5.1 6.3
