Given that the average of a set of data: - 1, x, 1, 2, 0 is 1, then the median of this set of data is () A. 1B. 0C. -1D. 2

Given that the average of a set of data: - 1, x, 1, 2, 0 is 1, then the median of this set of data is () A. 1B. 0C. -1D. 2

The average of ∵ - 1, x, 1, 2, 0 is 1, ∵ (- 1 + X + 1 + 2 + 0) △ 5 = 1, the solution is: x = 3, rearrange the data from small to large: - 1, 0, 1, 2, 3, the number in the middle is: 1, ∵ median is: 1
