Question

Two collaborators, Nicolas and Felipe, are talking about the order they received with the size of four new pieces that will be produced.

Each of the collaborators received the request on a piece of paper, but both were careless and ended up missing some information. Before asking for information about the order, they decided to talk and try to find out which measures were missing.

Nicolas' paper only has the average length, which is 17.2 meters. The paper with the order that Felipe has, about the same pieces, contains the information that the median length is 17.0 meters.

From the data they have, they were able to correctly conclude that the average between the lengths of the largest and smallest piece is:

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
