Question 1201748
<font color=black size=3>
You listed 37 values instead of 40.


The stem-and-leaf plot will consist of two columns: a stem on the left, and leaf on the right.


The stems in this case will be the tens place value.
The possible stems are: 2, 3, 4, 5, 6


First we need to sort the data
Original data set
{
68,49,47,38,52,47,49,24,57,69,55,49,69,
65,55,49,57,27,33,65,49,30,35,48,34,27,46,
64,33,38,40,21,33,47,38,31,56
} 


Sorted data set
{
21,24,27,27,30,
31,33,33,33,34,
35,38,38,38,40,
46,47,47,47,48,
49,49,49,49,49,
52,55,55,56,57,
57,64,65,65,68,
69,69
}


We can rearrange things so that each new stem gets its own line
{
21,24,27,27,
30,31,33,33,33,34,35,38,38,38,
40,46,47,47,47,48,49,49,49,49,49,
52,55,55,56,57,57,
64,65,65,68,69,69
}


Erase each tens digit and erase each comma
1477
0133345888
06777899999
255677
4558969


That represents the leaf values to be placed in the 2nd column of the stem-and-leaf plot.
The stems will be the tens digits we erased.
<table border = "1" cellpadding = "5"><tr><td>stem</td><td>leaf</td></tr><tr><td>2</td><td>1477</td></tr><tr><td>3</td><td>0133345888</td></tr><tr><td>4</td><td>06777899999</td></tr><tr><td>5</td><td>255677</td></tr><tr><td>6</td><td>4558969</td></tr></table>
This is another slightly different way to write out the table.
