Letdenote the median value of a random variable. Suppose you use the following definition of the median as the value of the random variable that satisfies the property:. That means you should array the values of the random variable from smallest to biggest values, and then accumulate probabilities for those values of the random variable until your accumulation reaches or tips over .5. Then stop as soon as your accumulation of probability reaches or tips over .5; you have found the median.

Alternatively, you could use the definition of median. That means you should array the values of the random variable from biggest values to smallest values, and then accumulate probabilities for those values of the random variable until your accumulation reaches or tips over .5. Then stop as soon as your accumulation of probability reaches or tips over .5; you have found the median.
