Question

70 students marks are represented with class intervals in a frequency distribution table. You are given the ogive for this data set. If you are going to find the median value then what will be the calculated mark you need to know to draw the horizontal line from y-axis?

• A. 35
• B. 45
• C. 40
• D. 20

Answer 1

The correct option is A 35

Since n = 70,

$Median=(\frac{n}{2}{)}^{th}term$
= $(\frac{70}{2}{)}^{th}term$
= ${35}^{th}term$

Through mark 35 on y-axis need to draw a horizontal line which meets the ogive at a certain point.
