... no mode exists; for example with the set {2, 4, 7, 8, 9, 11}. The set {2, 3, 3, 3, 4, 5, 6, 6, 6, 7} has two modes 3 and 6 because each occurs three times. One mode ⇒ “unimodal”. Two modes ⇒ “bimodal”. More than two modes ⇒ “multimodal”. • The mid-range is given by the average of the minimum and max ...

For example, if I obtain the results T T HHT T H, I record the number 7. What is: (a) [2] the probability that this experiment requires exactly 7 tosses? (b) [2] the pro ...
