Working
  1. Sorted: 29.9, 30.8, 31.2, 32.5, 33.6, 34.1
  2. Mean = sum ÷ count = 192.1 ÷ 6 = 32.0167
  3. Median = middle value (average of the two middle values) = 31.85
  4. Sample variance = Σ(x − mean)² ÷ (n − 1) = 13.7083 ÷ 5 = 2.7417; standard deviation = √2.7417 = 1.6558
  5. Range = 34.1 − 29.9 = 4.2
