Answer
Stem and leaf plot
Work Step by Step
First of all, you must sort the numbers.
$761, 768, 768, 776, 785, 785, 788$
Create a key for your Stem and leaf plot. In this case, I will use
$76|1=761$
Create a stem and leaf plot and on the left side, put
$76$
$77$
$78$
This represents the hundreds and the tens place.
On the right side, put the ones place of each number on the side of the appropriate tens place.
