Sir Alfonse sent out five students to measure a distance between two points marked on the ground using their pace factor. The students came up with the following five different values: 50.13, 47.90, 51.04, 50.47, and 48.22 meters. Assuming these values are equally reliable and that variations result from accidental errors, determine the most probable value of the distance measured.
