Class Frequency ------ 0–20 6 20–40 10 40–60 16 60–80 12 80–100 6 (Classes are continuous: a –b means a le x < b.) Using Median = l + hf ( n2 - c ), the median is:

  1. 51.25
  2. 60
  3. 40
  4. 53.8
Answer

A) 51.25

n = 50, n2 = 25. The median class is 40 –60 with l = 40, h = 20, f = 16, c = 16. Median = 40 + 2016(25 - 16) = 51.25. SLO M-09-C-02 · Understanding
