The two stem plots (with and without splitting the leaves) are plotted below using the data given in the attached picture :
The stem and leaf plots are given below:
Rounding the data to the nearest 10;
The values obtained are :
630, 670, 740, 650, 710, 740, 720, 700, 650, 600, 780, 780, 790, 810, 830, 860, 860, 900, 810, 790, 790, 960, 870
Ordering the data allows for easier generation of the plot.
Ordered data : 600, 630, 650, 650, 670, 700, 710, 720, 740, 740, 780, 780, 790, 790, 790, 810, 810, 830, 860, 860, 870, 900, 960
The stem plot without splitting :
STEM __ LEAF
6 ___ 00, 30, 50, 50, 70
7 ___ 00, 10, 20, 40, 40, 80, 80, 90, 90, 90
8 ___ 10, 10, 30, 60, 60, 70
9 ___ 00, 60
KEY : 6 | 00 = 600
The stem plot WITH splitting :
STEM __ LEAF
6 ___ 00, 30
6 ___ 50, 50, 70
7 ___ 00, 10, 20, 40, 40
7 ___ 80, 80, 90, 90, 90
8 ___ 10, 10, 30
8 ___ 60, 60, 70
9 ___ 00
9 ___ 60
KEY : 6 | 00 = 600
The stem plot with splitting gives a cleaner and more arranged output of the data as the values aren't congested on a single line.
