Question

The dotplot below displays 26 students’ scores on a 30-point statistics quiz. Which of the following statements best describes the dotplot? a. The distribution is skewed left with a center around 24. b. The distribution is skewed right with a center around 24. c. The distribution is unimodal symmetric with a center around 24. d. The distribution is unimodal symmetric with a center around 26.

Answer 1

The dotplot depicting the scores of 26 students on a 30-point statistics quiz indicates that the distribution is skewed left with a central tendency around 24.

Step-by-step explanation:

In the dotplot, the majority of dots are concentrated on the left side, suggesting lower scores, while the right side has fewer dots, indicating higher scores. This pattern is characteristic of a left-skewed distribution.

The center around 24 is inferred from the clustering of dots towards the lower end of the scale, suggesting that 24 is a common score for the students.

Therefore, the distribution is best described as skewed left with a center around 24.
