The Median Life Function
Median life,$$\breve{T}$$ is the value of the random variable that has exactly one-half of the area under the $$pdf$$ to its left and one-half to its right. The median is obtained from:


 * $$\int_{-\infty}^{\breve{T}}f(t)dt=0.5$$

For sample data, e.g. 12, 20, 21, the median is the midpoint value, or 20 in this case.
