Mean(平均数):The mean is the sum of all the numbers divided by the total number of numbers. It gives an average value of the numbers. Median(中位数):The median is the middle number in a set of numbers when they are arranged inascending or descending order. If there are an odd numbe...
Medianwhich is the middle number of a group of numbers; that is, half the numbers have values that are greater than the median, and half the numbers have values that are less than the median. For example, the median of 2, 3, 3, 5, 7, and 10 is 4. ...

Mean is found by evening out the numbers 2, 5, 2, 1, 5 mean = 3 6th Grade How to Find the Mean of a Group of Numbers Step 1 – Add all the numbers. 8, 10, 12, 18, 22, 26 8+10+12+18+22+26 = 96 6th Grade How to Find the Mean of a Group of Numbers Step 2 – Di...
Finally we let the median be x. (35+x)/5=x ⟹ 35+x=5 x ⟹ x=(35)/4=8.75, and the sequence is 4,6,8,8.75,17, which has median 8 . Therefore this case is not valid again.Hence the only possible value of x is ()-5....
