Math Problem Statement

Berpandukan Jadual 4 di atas, tanpa melukis ogif, hitungkan median. (7 markah)

Solution

The problem asks to calculate the median based on data in "Jadual 4" without plotting an ogive. To proceed, I'll need the specific data from Jadual 4 (e.g., class intervals, frequencies). Could you provide that information, or should I assist based on a general example?

Let me know how you'd like to proceed! Meanwhile, here are some general steps to calculate the median in grouped data:

  1. Find the cumulative frequencies of the data.
  2. Identify the median class, where N2\frac{N}{2} (where NN is the total frequency) falls.
  3. Apply the median formula: Median=L+(N2CFf)×c\text{Median} = L + \left( \frac{\frac{N}{2} - CF}{f} \right) \times c Where:
