Question

Make an ordered stem-and-leaf plot of the data.

$13.5,\text{15.7,15.0},\text{12.6},\text{14.2},\text{15.1},\text{18.0},\text{13.9},\text{15.2},\text{14.1},\text{12.5},\text{12.1},\text{13.4}$

Short answer

The ordered stem-and-leaf plot is,

$\begin{array}{ccccc}12& 1& 5& 6& \\ 13& 4& 5& 9& \\ 14& 1& 2& & \\ 15& 0& 1& 2& 7\\ 16& & & & \\ 17& & & & \\ 18& 0& & & \end{array}$

Step-by-step solution

Step 1. Given Information.

The provided numbers are,

$13.5,\text{15.7,15.0},\text{12.6},\text{14.2},\text{15.1},\text{18.0},\text{13.9},\text{15.2},\text{14.1},\text{12.5},\text{12.1},\text{13.4}$

Step 2. Calculation.

To find the ordered stem-and-leaf plot of the data write the stem first. The tens’ digits and the ones’ digits of the data values be the stems.

Then, record each leaf by writing its tenths’ digits on the same line as its corresponding stem.

$\begin{array}{l}\text{Orderedplot}\\ \\ \begin{array}{ccccc}12& 1& 5& 6& \\ 13& 4& 5& 9& \\ 14& 1& 2& & \\ 15& 0& 1& 2& 7\\ 16& & & & \\ 17& & & & \\ 18& 0& & & \end{array}\end{array}$

Step 3. Conclusion.

The ordered stem-and-leaf plot is,

$\begin{array}{ccccc}12& 1& 5& 6& \\ 13& 4& 5& 9& \\ 14& 1& 2& & \\ 15& 0& 1& 2& 7\\ 16& & & & \\ 17& & & & \\ 18& 0& & & \end{array}$
