The Runs test results in rejecting the null hypothesis of randomness when______________?
Correct answer: D. Either of the above
- A. There is an unusually large number of runs
- B. There is an unusually small number of runs
- C. None of these
- D. Either of the above
Explanation
Random sequences tend to produce a typical number of runs; both an unusually small number and an unusually large number indicate nonrandom ordering. Therefore, either extreme can lead to rejection of randomness.
