Answer:
Mean
Step-by-step explanation:
To calculate the mean you have to sum the values and then divide them by the number of values; for example, if you have 1 and 10, the mean will be 1+10 = 11, then 11/2 = 5.5, the mean is 5.5. The mean is affected by the highest value. If we continue summing high values, the mean will go grow, for example, if you have 1, 10, 10, the mean will be, 1+10+10 = 21 then 21/3 = 7. The mean is 7, and it is closer to 10 than 1.
As the reporter wants to show they are overpaid, the mean will give a number that its affected by the highest value, in this case, the player with a higher salary.
