A q for median, 97 students take apart in a test and the median score is 85 which of the following descriptions is correct?
1) At least 49 students’score are equal to or more than 85
2) At least 49 students’score are less than 85
3) At most 49 students’score are equal to or more than 85
I think those two question are similar. |
