It looks symmetrical to me, but the question is highly subjective. Who gets to decide what is considered "skewed" or "symmetrical"?
You are correct that determining whether a distribution is skewed or symmetrical can be subjective to some extent. In statistical analysis, there are various methods and tests available to assess the symmetry or skewness of a distribution. These methods rely on mathematical calculations and statistical measures, such as the skewness coefficient or histogram analysis.
However, without additional information or specific guidelines provided by the teacher, the decision could be open to interpretation. It would be best to consult with your group members or seek clarification from your teacher to come to a consensus on how to categorize the distribution.
