Question

which is a negatively skewed distribution? a. dot plot, b. dot plot, c. box plot, d. histogram

Explanation:

A negatively skewed distribution (left - skewed) has a long tail on the left side (lower values) and the bulk of the data on the right (higher values).

• Option A: The data has a long tail on the right (higher values), so it is positively skewed.
• Option B: The data is symmetric around the center, so it is a symmetric distribution.
• Option C: The box - plot shows that the left whisker is long (lower values) and the data is concentrated on the right (higher values), which is characteristic of a negatively skewed distribution.
• Option D: The histogram is symmetric around the center, so it is a symmetric (approximately normal) distribution.

Answer:

C. The box - plot with a long left whisker and data concentrated on the right (representing a negatively skewed distribution)
