<h3>What is a Stem-and-leaf Plot?</h3>A stem-and-leaf plot is a table which is used to display a set of data in such a way that, on the left we have the "stem" which displays the first digit or digits of a data value.
On the right, we have the 'leaf' which displays the last digit of the data value.
For example, if we are to represent "25" and "26" on a stem-and-leaf plot, we would have: 2 | 5, 6.
Therefore, the stem-and-leaf plot for 29,22,21,6,13,6,17,29,26,9,16,10,25,3,2,23,13,10,7,16,29,30,4,11,7,28,27,22,10 is shown in the image attached below (see attachment).
