What measuring tool is used to visually inspect the form, or shape, of an external thread?
Suppose that the length of the steel bar is measured by a number of different observers and following set of 11 measurements is recorded as set A (units mm): 398, 420, 394, 416, 404, 408, 400, 420, 396, 413, 330. Next the measurements are taken using different ruler to produce measurement set B: 409, 406, 402, 407, 405, 404, 407, 404, 407, 407, 408. It can be shown that the mean values set A and B are 409 and 406 respectively. Which of the two measurement sets A and B, and the corresponding mean value, should have most confidence in? why? Text
