which statement below best describes the shape of distribution (c)?

skewed and multimodal distribution
unimodal distribution

Explanation:

⚡ Using what you learned: Describing Distributions

Step 1: Analyze Distribution (a)

• Observation: The graph has two distinct peaks (modes) of roughly equal height and is symmetric from left to right.
• Classification: Bimodal distribution.

Step 2: Analyze Distribution (b)

• Observation: The graph has a single, clear peak in the center and is symmetric.
• Classification: Unimodal and symmetrical distribution.

Step 3: Analyze Distribution (c)

• Observation: The graph has more than two peaks (multiple local maxima), making it multimodal. Additionally, the tail stretches out further to one side (it is not symmetric), meaning it is skewed.
• Classification: Skewed and multimodal distribution.

Answer:

• For the first question (distribution a): Bimodal distribution
• For the second question (distribution c): Skewed and multimodal distribution
