The Average Height
The average height of members of the high school basketball team is six feet, three inches. Jerry is on the high school basketball team, so Jerry must be taller than six feet. The argument above is flawed because it confuses (Points : 1)
The argument presented in the statement asserts that because the average height of the high school basketball team is six feet, three inches, and Jerry is a member of the team, he must be taller than six feet. While this might initially seem logical, it is critically flawed because it confuses the concepts of average height with individual height. The key misunderstanding arises from assuming that an individual's height must be above the average simply because they are part of a group whose average exceeds a certain threshold.
In statistical terms, the average height is calculated by summing the heights of all team members and dividing by the total number of members. The average provides a measure of central tendency, but it does not dictate that every individual member surpasses this average. Indeed, in any group, some members will be taller than the average, and some will be shorter. The existence of members shorter than the average is a natural consequence of how averages work, especially in normally distributed traits such as height.
Therefore, the argument that Jerry must be taller than six feet because he is on the team with an average height of six feet, three inches, is invalid. It assumes a unanimity among team members that does not exist. The fact that the average exceeds six feet does not guarantee Jerry's height is above this threshold; he could be shorter than the average and still be on the team.
This misunderstanding is a common logical fallacy known as the "faulty attribute association," which incorrectly attributes the properties of the group (the average) to each individual member. A more accurate claim would be that some members—possibly Jerry among them—are taller than the average, but it is not necessarily true that Jerry himself is taller than six feet.
In conclusion, the flaw in the argument lies in the mistaken belief that all individual members, including Jerry, must exceed the average height. Recognizing that averages summarize the entire distribution, but do not define individual characteristics, clarifies the invalidity of this reasoning.
