Answer 1

The median is the middle value when the numbers are put in numerical order.

In this case, the numbers of siblings given are: 0, 1, 2, 2, 3, 3, and 5.

When put in numerical order, the numbers are: 0, 1, 2, 2, 3, 3, 5.

Since there are 7 numbers in total, the median would be the 4th number when in numerical order, which is 2.

Therefore, the median number of siblings is 2.
