Question

the parallel boxplots below display the quiz grades (out of 30) for two of mrs. smiths statistics classes. which class performed better on this quiz? class 1 performed better because their scores ranged from 12 to 30. class 1 performed better because their median score is higher than the median score for class 2 class 2 performed better because their median score is higher than the median score for class 1. class 2 performed better because the distribution of quiz grades is approximately symmetric

Explanation:

En un diagrama de caja, la mediana es una medida clave. Si la mediana de una clase es más alta, significa que la mayoría de los estudiantes de esa clase tiene una puntuación más alta. Aunque la simetría o el rango pueden ser factores, la mediana es una medida más directa de cómo se desempeñan los estudiantes en general.

Answer:

Class 2 performed better because their median score is higher than the median score for class 1.
