Relative Frequency and Percent Frequency Distribution

Relative Frequency Calculations

• Relative frequency represents the proportion of total observations belonging to a specific category, derived from Table 2.4 (also referenced as Table 2).
• Coca-Cola Relative Frequency:
  • Expression and calculation:     $\frac{19}{50} = 0.38$
• Diet Coke Relative Frequency:
  • Expression and calculation:     $\frac{8}{50} = 0.16$

Percent Frequency Distribution and Aggregate Analysis

• Percent frequency converts relative frequency values into percentage representation:
  • Coca-Cola accounts for $38\%$ of total purchases.
  • Diet Coke accounts for $16\%$ of total purchases.
• Aggregate Market Share of Top Three Soft Drinks:
  • The combined percent frequency for the top three soft drinks is computed by summing their individual percentages:     $38\% + 26\% + 16\% = 80\%$
  • The top three soft drinks collectively account for $80\%$ of all soft drink purchases.
