Measurements of some variable X were made at an interval of 1 minute from 10 A.M. to 10:20 A.M.. The data, thus, obtained is as follows:
X:60,62,65,64,63,61,66,65,70,68,63,62,64,69,65,64,66,67,66,64,50.
The value of X which is exceeded 50% of the time in the duration of measurement, is
(i) 69
(ii) 68
(iii) 67
(iv) 66

Answer:
It is a multiple choice question and it is general knowledge question.
The answer is 68.
But I am unable to understand the question. What exactly says the question?

With the given data,
X:60,62,65,64,63,61,66,65,70,68,63,62,64,69,65,64,66,67,66,64,50
68 is the data collected at 10:10 which is the middle of time interval 10:00 to 10:20
That is the only interpretation which makes the answer 68 otherwise, 68 is not the median of your data at all.

Isn't the question maybe written badly? I could think the author meant:
The value of X at which 50% of the time in the duration of measurement is exceeded
Clearly if this is an exam question, I would definitely consider the question as void, as it is unclear.
