Formula: Average = sum of all observations/Total number of all observations. Calculation: Mean of 50 observations = 36. Sum of 50 observations = 36 × 50 = 1800. Correct sum of 50 observations = 1800 - 23 + 48 = 1825. Correct mean of 50 observations = 1825/50 = 36.5. Short Trick: how high should a shower niche be installed
