The standard deviation (sd) is calculated by finding the square root of the variance. First, find the mean of the differences: (0.4 + 0.24 + 0.22 + 0.26 + 0.34) / 5 = 0.292. Then, calculate the variance: [(0.4-0.292)² + (0.24-0.292)² + (0.22-0.292)² + (0.26-0.292)² + (0.34-0.292)²] / 5 = 0.0064. The standard deviation is the square root of 0.0064, which is 0.08.
