Study Notes: Relationship

Free study material for CA Foundation Business Mathematics, Logical Reasoning and StatisticsSeating Arrangements

Relationship between mean, median, mode: In symmetric distribution: mean = median = mode. In right-skewed: mean > median > mode (tail pulls mean right). In left-skewed: mean < median < mode (tail pulls mean left). Empirical relationship: Mode ≈ 3 × Median - 2 × Mean. Example: Salaries {20, 22, 24, 26, 50}. Mean = 28.4, Median = 24, Mode = none. Right-skewed (outlier 50). Using formula: Mode ≈ 3×24 - 2×28.4 = 72 - 56.8 = 15.2. Solving: Calculate all three measures. Compare to identify skewness. Use formula for estimation. Exam tip: Understand distribution shape from measures. Mean sensitive to outliers; median robust. Choose measure based on data distribution.
