After gathering data on the number of siblings my classmates have, I noticed that most of them either have no siblings or just one, but a few have many more. This creates a skewed distribution because the higher numbers pull the average up. Therefore, the median is a better center measure because it isn't affected by those few students with many siblings.
To calculate, let's say my classmates reported the following number of siblings: 0, 1, 1, 2, 3, 4, 5. The mean is found by adding them together (0 + 1 + 1 + 2 + 3 + 4 + 5 = 16) and dividing by the total number of classmates (7), which gives us a mean of about 2.29. The median, though, is the middle number when the data is in order, which is 1.
In this case, the best measure of center for the number of siblings is the median because it better represents most of my classmates without being influenced by the few with many siblings.
