For even number of observations of a data distribution, what is the median? rank on the ascending order of observations b) (n/2) rank on the ascending order of observations c) Average of (n/2)th observation and (n/2 + 1)th observation d) Average of and (n/2) rank on the ascending order of observations

For even number of observation (n) of a data variation, the median is Average of (n/2)th observation, and (n/2 + 1)th observation. This is because median of a data distribution is the fiftieth percentile of the data distribution.
