SUMMARY
The discussion centers on calculating the average value and standard deviation of five measurements of an object's height, which are 11.25 cm, 11.20 cm, 11.22 cm, 11.18 cm, and 11.25 cm. The average value calculated is 11.22 cm, and the standard deviation is determined to be 0.03 cm. However, the correct answer according to the textbook is B, h = (11.22 ± 0.04) cm, as the range of values indicates that the smallest measurement (11.18 cm) falls within this range. This highlights the importance of considering the range of measurements rather than solely relying on standard deviation.
