Given values are 7, 19, 19, N, 15
Their mean is given to be 13.
Which means the sum of the given values divided by 5 = 13
==> (7 + 19 + 19 + N + 15)/5 = 13
==> (60 + N)/5 = 13
==> 60 + N = 65 [multiplying by 5 on both the sides]
==> 60 + N - 60 = 65 - 60
==> N = 5
So the unknown value = 5.
Mean is nothing but the average of the given values.
To find the median we first arrange these values in one order.
That is ascending or descending.
==> 5, 7, 15, 19, 19
The middle value is called the median
Here the median = 15.
Mode is the most frequantly occured value.
Here 19 is repeated and so mode = 19.
Good Luck!!!
