2. The scores are evenly distributed in the distribution.

Rationale 1: If there are more scores at the lower end of the distribution and the tail points to the right, it is positively skewed.
Rationale 2: Scores are evenly distributed in a nonskewed or normal distribution.
Rationale 3: Scores clustered around the mean would not result in a skewed distribution.
Rationale 4: In a negatively skewed distribution there are more scores at the upper end of the distribution and the tail of the distribution points to the left.
