So the tight fit of the null distribution suggests that the rankings are, if not entirely random, then darn close.

Remember, the null distribution shows what program rankings would look like if they were entirely random.

To highlight the role of random error, we calculated the «null distribution,» or what the distribution of program rankings would look like if all the programs were actually identical and nothing but random estimation error were present.

In fact, when we lay the null distribution over the Texas results, the fit is almost perfect (see Figure 3).
