Question

In a stem and leaf plot diagram, a key is used to represent any data points.
$\text{Key}:10|1$ signifies -

• A. $1$
• B. $10$
• C. $101$
• D. It is not a valid key.

Answer 1

The correct option is C $101$

Consider a stem and leaf plot is as follows: Stem Leaf

$0$ $5$ $10$	$0$ $0,3$ $1,5$

Here, the data points are the numbers of the stem column followed by the corresponding number in the leaf column.
Example:


$1^{st}$ row respresents: 00
$2^{nd}$ row respresents: 50, 53
$3^{rd}$ row respresents: 101, 105

$\therefore \text{Key}:10|1$ means $101.$
