The marks of 7 students in a unit test are given below :
9, 10, 7, 6, 9, 3, 5
Median of the data is :
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 7
The median is the middle value once the observations are arranged in order. With an odd number \(n\) of observations, it is the \(\left(\frac{n+1}{2}\right)^{\text{th}}\) value.
In ascending order: 3, 5, 6, 7, 9, 9, 10
\(n=7\), so the median is the \(\left(\frac{7+1}{2}\right)^{\text{th}}=4^{\text{th}}\) value
The 4th value is 7
