Question

In an orchard, the quantity of apples yield by 4 trees are represented in a bar graph. Determine the median of the data set.

• A. 50 apples
• B. 60 apples
• C. Both (a) and (b) above.
• D. 55 apples

Answer 1

The correct option is D 55 apples

The tabular representation of the given bar graph is as follows: $N^{th}$ Tree Number of Apples Yield

$1^{st}$ Tree	40
$2^{nd}$ Tree	70
$3^{rd}$ Tree	50
$4^{th}$ Tree	60

To find median, we need to arrange the data in ascending/decending order.

The data set in ascending order$\to$ $N^{th}$ Tree Number of Apples Yield

$1^{st}$ Tree	40
$3^{rd}$ Tree	50
$4^{th}$ Tree	60
$2^{nd}$ Tree	70

As the number of data points is 4 i.e., even, median is the average of two middle numbers (50 and 60)
$\therefore \text{Median =}\frac{50+60}{2}=55\text{apples}$
