Question 1089615
Here is one example  { 70, 72, 86, 74, 102, 95, 89 }

mean = (70+72+86+74+102+95+89) / 7 = 588 / 7 = 84
median is found by sorting them { 70, 72, 74, 86, 89, 95, 102 }  and choosing the middle value (86).
[ If two middle values exist, for example for an even number of data points, then average them. ]
