Mathematics - Statistics - Measures of Center - Mean, median, mode - Three Measures Step by Step
8 steps using the dataset {3, 5, 5, 7, 8, 10, 12}: (1) MEAN: Add all values: 3+5+5+7+8+10+12 = 50. (2) Divide by count: 50 ÷ 7 ≈ 7.14. That's the mean (average). (3) MEDIAN: First, arrange in order (already done). (4) Find the middle value: 7 values → 4th value = 7. That's the median. (5) What if ev
