What is Business Statistics in BBS?

Business Statistics is a core subject for BBS 1st Year students under Tribhuvan University. It focuses on data collection, presentation, analysis, and interpretation to support business decision-making. Topics include measures of central tendency (mean, median, mode), dispersion, skewness, correlation, probability, and index numbers like Laspeyres and Paasche, all tested in the 2082 model question.

Key Formulas for Business Statistics

Master these essential formulas to solve questions in the 2082 model paper:

Mean (Arithmetic Average):
- Ungrouped Data: Mean = (Sum of all values) / Number of values
- Grouped Data: Mean = Σ(f × x) / Σf (f = frequency, x = mid-point of class)
Median:
- Ungrouped Data: Median = Middle value (for odd n) or Average of two middle values (for even n)
- Grouped Data: Median = L + [(n/2 – cf) / f] × h (L = lower boundary, cf = cumulative frequency, f = frequency, h = class width)
Mode:
- Ungrouped Data: Mode = Most frequent value
- Grouped Data: Mode = L + [(Δ1) / (Δ1 + Δ2)] × h (L = lower boundary, Δ1 = frequency difference with previous class, Δ2 = frequency difference with next class, h = class width)
Measures of Dispersion:
- Range: Range = Maximum value – Minimum value
- Quartile Deviation: QD = (Q3 – Q1) / 2 (Q1 = lower quartile, Q3 = upper quartile)
- Standard Deviation: σ = √[Σ(x – Mean)² / n] (for population) or s = √[Σ(x – Mean)² / (n-1)] (for sample)
Skewness:
- Karl Pearson’s Coefficient: Skewness = (Mean – Mode) / Standard Deviation or Skewness = 3(Mean – Median) / Standard Deviation
Index Numbers (Laspeyres and Paasche):
- Laspeyres Price Index: L = [Σ(p₁ × q₀) / Σ(p₀ × q₀)] × 100 (p₁ = current price, p₀ = base price, q₀ = base quantity)
- Paasche Price Index: P = [Σ(p₁ × q₁) / Σ(p₀ × q₁)] × 100 (q₁ = current quantity)

Tips to Score Well in Business Statistics

Master key formulas (e.g., mean, standard deviation, skewness, Laspeyres index).
Practice TU model questions and past papers regularly.
Use a non-programmable scientific calculator to save time.
Show clear steps with proper headings in calculations.
