Given that the average of a group of numbers x, 5, 0, 3, - 1 is 1, then its median is 1______ .

Given that the average of a group of numbers x, 5, 0, 3, - 1 is 1, then its median is 1______ .

∵ (x + 5 + 0 + 3-1) △ 5 = 1, ∵ x = - 2, ∵ data from small to large are - 2, - 1, 0, 3, 5, then the median is 0
