Given:
Observations (in ascending order): 6, 9, 15, x + 4, x + 8, x + 12, 30, 32
Median of the data is 19.
Formula Used:
For an even number of observations, the median is the average of the two middle terms.
Median =
Solution:
The 4th term is x + 4 and the 5th term is x + 8
So, Median =
Since the median is given as 19
x + 6 = 19
Therefore, x = 19 - 6 = 13
