Options

• ATransformed
• BMulti-skewed
• CBi-attribute
• DBimodal

• A
  5% (2)
• B
  16% (6)
• C
  8% (3)
• D
  71% (27)

Explanation

A histogram with two distinct peaks indicates a bimodal distribution (D), meaning the data has two separate modes - two values or ranges where data clusters most frequently. This often occurs when two different subgroups are mixed in one dataset (e.g., heights of men and women combined).

Why the distractors are wrong:

• A (Transformed) - transformation is a data manipulation technique, not a shape descriptor.
• B (Multi-skewed) - "multi-skewed" is not a real statistical term; skewness describes asymmetry, not the number of peaks.
• C (Bi-attribute) - not a distribution shape term; attributes describe data characteristics, not histogram patterns.

Memory tip: "Bi" = two, "modal" = mode (peak). Two peaks → two modes → bimodal. Just count the peaks and match the prefix: one peak = unimodal, two peaks = bimodal.
