The mean is calculated by summing all the weights and dividing by the total number of children, which gives 44.85714. The median, being the middle value in an ordered list, is 44 (the average of the 25th and 26th values since there are 50 values in total). The mode, the most frequently occurring value, is 58, as it appears three times.
