Real-World Examples
Case Study 1: Sales Data
Consider the following sales data: 10, 0, 15, 5, 0, 20. Using our calculator, the average excluding zeros is (10+15+5+20)/4 = 13.75.
Case Study 2: Exam Scores
In an exam with scores: 85, 0, 90, 70, 0, 95, the average excluding zeros is (85+90+70+95)/4 = 85.75.
Case Study 3: Stock Prices
For stock prices: 120.50, 0, 125.75, 118.25, 0, 123.10, the average excluding zeros is (120.50+125.75+118.25+123.10)/4 = 122.46.
