Question

While determining median of a data set from stem and leaf plot, the numbers in the leaf column are arranged in ascending order by -

• A. considering all the numbers at a time, i.e., with inter-row arrangement.
• B. considering the number within each row, i.e., intra-row arrangements only.

Answer 1

The correct option is B considering the number within each row, i.e., intra-row arrangements only.

Consider arranging the following stem and leaf plot in ascending order. Stem Leaf

$1$ $2$ $4$	$9,0,1,9$ $3,0,0$ $1,5,6$

$\text{key}:1|1$ means $11$

The data points are obtained by merging the stem number with corresponding leaf numbers.
Example:

Also, each row in a leaf colum corresponds to the same number in the stem column
.
$\therefore$ While arranging the digits, we compare the digits in the same row.

The arranged data is: Stem Leaf

$1$ $2$ $4$	$0,1,9,9$ $0,0,3$ $1,5,6$
