The correct answer is: C. B, A and C
The consistency of a player is measured by the standard deviation of their scores. A lower standard deviation indicates that the player’s scores are more consistent, while a higher standard deviation indicates that the player’s scores are more variable.
In this case, player B has the lowest standard deviation, followed by player A and then player C. This means that player B’s scores are the most consistent, followed by player A and then player C. Therefore, the players in descending order of consistency are:
- B
- A
- C
Here is a table showing the scores of each player and their standard deviation:
Player | Average score | Standard deviation
——- | ——– | ——–
A | 40 | 5
B | 75 | 10
C | 90 | 18
As you can see, player B has the lowest standard deviation, followed by player A and then player C. This means that player B’s scores are the most consistent, followed by player A and then player C.
