What are the three properties of frequency distribution?

• A. Mean; Median; Mode
• B. Central location (peak); Spread (data dispersal); Shape (normal, log normal, etc.)
• C. Variance; Skewness; Kurtosis
• D. Outliers; Range; Standard deviation

Answer: (B)

Describing a frequency distribution relies on three aspects: where the data cluster (central location or peak), how much they spread (spread or variability), and the overall form of the distribution (shape, such as normal, skewed, or log-normal). This trio is best captured by central location (the peak), spread (data dispersal), and shape (the distribution’s form). Other options mix in specific statistics like measures of center or variability, or focus on extremes and single descriptors, which don’t describe all three core features together.
