Question

identifying symmetrical and non-symmetrical distributions

which of the distributions is right skewed?

Explanation:

Define right-skewed distribution

A right-skewed distribution has a long tail extending to the right. Most data points are concentrated on the left side.

Analyze the first histogram

The first histogram (values 1 to 11) has a peak on the right side. The tail extends to the left. This is left-skewed.

Analyze the second histogram

The second histogram (values 20 to 31) has its highest peak on the left side. The tail extends to the right. This is right-skewed.

Analyze the third histogram

The third histogram (values 1 to 12) has its peak on the right side. The tail extends to the left. This is left-skewed.

Analyze the fourth histogram

The fourth histogram (values 30 to 41) is roughly symmetric around the center peak.

Answer:

• (A) First distribution (values 1 to 11)
• (B) Second distribution (values 20 to 31) (Correct answer)
• (C) Third distribution (values 1 to 12)
• (D) Fourth distribution (values 30 to 41)
