Martin enjoys playing video games. On his birthday he received “Man vs. Monsters” a game in which the player plays the role of a person who is trying to save the earth from an invasion of alien monsters. At the end of the game, the player either wins or loses. The first three times Martin played the game, he lost. In the next seven games that he played, he won four times, and he felt like his performance was improving. In fact, the sequence of Martin’s wins and losses is as follows, where “L” represents losing a game, and “W” represents winning a game. L, L, L, W, L, L, W, L, W, W Martin concluded he was getting better at the game the more he played, and he said that this sequence of wins and losses was evidence of his improvement. His sister Hannah, however, was not convinced. She said, “That sequence of wins and losses looks like a random list to me. If you were really getting better, why didn’t you lose the first six and then win the last four?” Consider that Hannah is correct and that Martin was not really getting better. He had six losses and four wins in a particular order and, if Hannah is correct, those wins and losses could have been arranged in any other order. According to Hannah, Martin’s results indicate how good he is at the game-he wins about 40% of the time-but do not indicate whether he is improving. One way to quantify improvement is to count how many wins occur among the last five games, and subtract the number of wins that occur among the first five games. Call this the “improvement score” for the sequence of results for ten games. Using this method to quantify improvement, what would a negative improvement score imply? What would a positive improvement score imply?
