For example, in a speech contest, a judge and a contestant who knew each other before or had a better feeling after the meeting will give him a very high score which is not very objective, and the removal of a maximum score can reduce the impact of this situation to a certain extent.
Similarly, if a judge gives a contestant a very low score in a very subjective manner, it will also be unfair, so the lowest score should be removed.
Taking the average score is closer to the contestant's true level.
Expanded Information
The arithmetic mean is the most basic and commonly used type of averaging indicator in statistics, and is divided into simple arithmetic mean and weighted arithmetic mean. It is mainly applicable to numerical data, not applicable to quality data. According to the different forms of expression, the arithmetic mean has different forms of calculation and calculation formula.
The arithmetic mean is a special form of weighted average (special in that the weights of each item are equal). In practical problems, when the weights of the items are not equal, the weighted average should be used to calculate the average; when the weights of the items are equal, the arithmetic average should be used to calculate the average.
The arithmetic mean is a good concentration of quantities, with responsive, strict, simple and easy to solve, simple calculation, suitable for further calculations and less affected by sampling variations and other advantages.
The arithmetic mean is susceptible to extremes of data because it is so responsive that a small or large change in each piece of data affects the final result.

Why is it necessary to remove a highest and a lowest score when calculating the average score?
The average reflects the general level of a set of data. Calculating the average score is a more intuitive and concise measure of the set of data. However, averages are also often affected by extreme data, so extreme data are often removed when calculating averages, which is what this question is talking about by removing one highest and one lowest score.
