1,5,16,13,13,2,16. find the mean, and median.

The numbers given to us are
1,5,16,13,13,2,16.

Their sum is 1 +5 + 16 + 13 + 13 + 2  +
16 = 66.

The sum divide by the total number of terms is the
mean. This is 66/7.

The median is the term that occurs in
the middle of the set if they are arranged in ascending or descending
order.

1,5,16,13,13,2,16

=>
1 , 2 , 5, 13, 13 , 16 , 16.

Therefore we see that 13 is
the term in the middle.

The required mean is
66/7 and the median is 13.
