Question

question
the graph below represents the number of siblings each student in a class has.
siblings
what was the median number of siblings?
answer attempt 1 out of 2
siblings

Explanation:

Step1: Calculate total number of students

Add up the frequencies: \(6 + 10+7 + 1+3 + 3=30\)

Step2: Find the position of the median

Since \(n = 30\) (even), the median is the average of the \(\frac{n}{2}\)th and \((\frac{n}{2}+ 1)\)th values. \(\frac{30}{2}=15\) and \(\frac{30}{2}+1 = 16\)

Step3: Cumulative frequency

For \(0\) siblings: cumulative frequency \(=6\)
For \(1\) sibling: cumulative frequency \(=6 + 10=16\)

Answer:

\(1\)
